A summary: “driverless cars are ‘probably’ legal”

Posted on by

An economist takes a look at existing law and argues driverless cars are probably legal:

Over at the blog Marginal Revolution, economist Tyler Cowen points to a recent research paper by Bryant Walker Smith, a fellow at Stanford Law School, who has made the legality of driverless cars his bailiwick. In offering “the most comprehensive discussion to date of  whether so-called automated, autonomous, self-driving, or driverless vehicles can be  lawfully sold and used on public roads in the United States,” Smith argues that driverless cars are “probably legal.” He concludes [PDF]:

Current law probably does not prohibit  automated vehicles — but may nonetheless discourage their introduction or complicate their operation.

Unlike many journalists and policy-makers, Smith begins his analysis with a presumption of legality instead of illegality. “Until legislators, regulators, or judges definitively clarify the legal status of automated vehicles, any answer is necessarily a guess,” he writes. Smith’s own guess turns on three “key legal regimes”: the 1949 Geneva Convention on Road Traffic, National Highway Traffic Safety Administration regulations, and vehicle codes in the 50 U.S. states.

Smith doesn’t think that any of these regimes expressly prohibits driverless cars. The Geneva Convention says a driver must be able to control a vehicle at all times, but that stipulation is probably satisfied if a human can override the automatic operation. N.H.T.S.A. rules don’t explicitly rule out driverless cars either — though an odd rule saying hazard lights must be “driver controlled” might be a sticking point.

States codes, meanwhile, “probably do not prohibit” driverless cars in Smith’s mind, but they do complicate the situation. Right now these codes all naturally presume the presence of a human driver; in New York, for instance, there’s a rule that drivers must keep one hand on the wheel at all times (who knew?) that could become a problem in an automated-vehicle world. Additionally, laws dictating a certain following distance might interfere with algorithms that keep driverless cars close together on the road.

Sounds like an interesting loophole – why worry about whether it is legal when you can instead ask whether it is illegal? I still think a lot of the issue with driverless cars comes down to people, both “drivers” (now people who can override the car’s autopilot when they want) and other people on the road around the driverless cars, adjusting to the change. If it is like other modern technologies, like smartphones, and drivers realize they might be able to do other things while driving, perhaps the switch may be quick.

Another thought: could driverless cars and electric cars end up prolonging and even extending urban sprawl? If commuting is easier and consumes fewer resources (still debatable considering what it takes to produce batteries), why not continue it?

Consumer Report says buyers don’t want exurban McMansions; they want other features

Posted on by

Consumer Reports lays out five features homebuyers want – and these five features are not usually associated with McMansions.

Homebuyers have become more practical since the housing market crisis—they don’t want cavernous entryways but they do want plenty of storage space. They want to be close to their jobs and integrated into their communities. And they want to keep their energy costs low. In today’s market, a McMansion in the exburbs may be a tough sell. Price is still primary, but if you’re thinking of buying or selling a home, you should learn how buyers’ preferences have changed since the last time you were in the market. Here are the five features today’s homebuyers want most.

Proximity to work…

Energy efficiency…

Lots and lots of storage…

Quality of space, not quantity…

Connection outdoors, and to the community beyond…

Perhaps this could be summed up as a McMansion double-whammy: not only did you buy a house that a lot of Americans criticize, now fewer people want to buy it from you which would help you leave such a house.

There are a couple options available to McMansion owners and builders:

1. Hunker down and find the segment of the real estate market that still wants McMansion. And there are still people who do.

2. Retrofit their existing McMansions. There might be some relatively easier fixes in the areas of energy efficiency or developing storage space. The location aspects or connecting to the surrounding community might be harder.

3. Take a decent loss on the McMansion and move on.

We’ll see what happens to aging McMansions. I don’t think this is going to happen in large numbers anytime soon but if they could be built quickly, could they also be torn down and replaced quickly?

Attempts to make cellphone towers look like trees may or may not work

Posted on by

Cellphone towers are ubiquitous parts of the modern landscape. Trying to make them look like trees…can be interesting.

South African photographer Dillon Marsh‘s compact photo series (all 12 Invasive Species images featured here) is a meditation on the weird, and small, variations of design in tree cellphone towers.

“In certain cases the disguised towers might not be noticed,” says Marsh. “But then an undisguised tower might not have been noticed either.”

An important chapter in the history of tree-shaped cellphone towers was written in South Africa. In the mid-’90s, Ivo Branislav Lazic (who worked for a telecommunications service company called Brolaz Projects) and his colleague Aubrey Trevor Thomas were commissioned by Vodacom to solve the visual pollution problem cellphones presented.

Lazic and Thomas came up with the world’s first palm tree cellphone tower. The Palm Pole Tower, made from non-toxic plastics, was installed in Cape Town in 1996…

Meanwhile, in the American Southwest, fledgling company Larson Camouflage was responding to similar style-sensitive network companies. Larson makes scores of different “trees” but it kicked everything off in 1992 with a naturalistic pine that concealed a disagreeable cell tower in Denver, Colorado. To dress up a cell tower in plastic foliage can cost up to $150,000, four times the cost of a naked mast. Marsh is skeptical about the need for high-tech camouflage.

My first thoughts in seeing these South Africa pictures is that the camouflage doesn’t look too bad. However, the towers/trees are simply too tall and don’t blend into the landscape. This is not a matter of bad design; the tower is taller than everything else.

This gets at a bigger question: why does this infrastructure have to be covered in the first place? We want cell phones but we don’t want to see the technology that it requires? I’m reminded of this sometimes when traveling into neighborhoods in Chicago. In many of these places, there is a tangle of electrical lines, alleys, and poles (street lights, signs, police cameras, traffic lights, etc.). Compared to the Loop or suburban neighborhoods which are more spread out or places where electric lines are buried, this can look ugly. But, it is part of city life and would be quite expensive to eliminate.

This doesn’t mean we have to settle for ugly cell phone towers. But, the alternatives may not be so great either.

A rise in cooperative housing in the United States

Posted on by

More American adults are living with strangers in order to make ends meet:

Two million Americans over the age of 30 now live with a housemate or roommate, and shared households make up 18 percent of U.S. households – a 17 percent increase since 2007.

One group of women sold their homes and bought a house together in Mount Lebanon, Pa., after they all got divorced…

McQuillin, Louise Machinist and Karen Bush call their home a “cooperative household.” Each woman has her own bedroom and bathroom, and they share the common areas of the house, chores and expenses…

In some co-housing communities, families buy smaller homes built around a common building that the entire community shares. Some include communal kitchens and recreation space.

There are more than 100 of the special developments across the nation. Some co-housing operations share housework and childcare duties.

This is a different approach than Going Solo – single-person households have been on the rise in the United States for years now. But, living with other people has benefits including economic sharing.

It would be interesting to ask those who are living in cooperative households if they would choose to do so if they had more economic resources. In other words, is money trumping common American concerns about individualism and privacy?

Argument: elite colleges offer MOOCs because they can afford to

Posted on by

Here is an interesting argument about MOOCs, massive open online courses, that a hot topic of discussion these days: elite colleges can offer them because they accrue status and can afford the financial losses.

Millions of people were already taking online courses in 2011, when The New York Times noticed that thousands were taking a Stanford course online. The MOOC surge has been driven by the warm feelings associated with elite American colleges. Brand equity is obviously the principal admissions criterion for edX and Coursera, and for Udacity by implication, with its pedigree of Stanford origination and Silicon Valley cool.

Ideally, this will allow elite colleges to profit from and enhance their brands at once. Penn can’t ever be Coca-Cola. Its brand is tied to the noble purpose of higher learning. If it’s seen as a crass profit-taker, the whole thing falls apart. Many observers have asked where the “business plan” is for Harvard, MIT, and other institutions leading MOOCs. That misses the point.

Elite colleges are ultimately in the business of maximizing status, not revenue. Spending a lot of money on things that return a lot of status isn’t just feasible for these institutions—it’s their basic operating principle. It’s not hard to make money when you’re already wealthy—witness the performance of the Harvard Management Company over the past 20 years. The difficult maneuver is converting money into status of the rarefied sort that elite institutions crave.

MOOCs offer that opportunity. Elite colleges are willing to run them at a loss forever, because of the good will—and thus status—they create. Free online courses whose quality matches their institutional reputation (a tall order, to be sure, but MOOC providers have strong incentives to get there) could ultimately become as important to institutional status as the traditional markers of exclusivity and scholarly prestige.

In other words, MOOCs offered by elite colleges can reinforce existing status structures where these elite schools can continue to amass resources, financial, knowledge-wise, and social status and still claim they are helping the masses. On the other hand, can takers of MOOCs use them as real stepping stones to move up in society?

Lincoln, Nebraska #1 city in well-being

Posted on by

A new survey from Gallup and Healthways puts Lincoln, Nebraska as the number one city in the U.S. for well-being:

Lincoln, Neb., had the highest Well-Being Index score (72.8) in the U.S. across the 189 metropolitan areas that Gallup and Healthways surveyed in 2012. Also in the top 10 are Boulder, Colo.; Provo-Orem, Utah; Ann Arbor, Mich.; Honolulu, Hawaii; Fort Collins-Loveland, Colo.; and Burlington-South Burlington, Vt…

At 60.8, Charleston, W.Va., had the lowest Well-Being Index score, displacing Huntington-Ashland, W.Va.-Ky.-Ohio, which held this position the two previous years. Huntington-Ashland’s score of 61.2 is up from 58.1 in 2010, which is the lowest score on record for any metro area across five years of data collection. Mobile, Ala.; Utica-Rome, N.Y.; Hickory-Lenoir-Morganton, N.C.; and Fort Smith, Ark.-Okla.; join Charleston and Huntington-Ashland as frequent occupants of the bottom 10 list each year…

Washington, D.C.-Arlington-Alexandria, Va.-Md.-W.Va., residents reported the highest wellbeing among the nation’s 52 largest metropolitan areas, defined as those with 1 million residents or more, followed by San Francisco-Oakland-Fremont, Calif. These two metros have been in the top five among large metro areas in each of the past five years…

The Gallup-Healthways Well-Being Index score is an average of six sub-indexes, which individually examine life evaluation, emotional health, work environment, physical health, healthy behaviors, and access to basic necessities. The overall score and each of the six sub-index scores are calculated on a scale from 0 to 100, where a score of 100 represents the ideal. Gallup and Healthways have been tracking these measures daily since January 2008.

Interesting as there are more cities from the Great Plains and Midwest than I expected.

A few thoughts about the methodology:

1. After all is added up across these six measures, there isn’t much variation between the top and the bottom. Lincoln had the highest score at 72.8 and Charleston had the lowest at 60.8. So on a scale of 0 to 100, the range was just 12. This suggests there is not much variation in these measures and that this index may not tell us a whole lot. Are Americans simply generally optimistic about these topics or are they realistically not that different across cities?

2. What exactly does Gallup and Healthways do with this information that it requires daily polling? This is not a small sample:

Results are based on telephone interviews conducted as part of the Gallup-Healthways Well-Being Index survey Jan. 2-Dec. 29, 2012, with a random sample of 353,563 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia, selected using random-digit-dial sampling.

Perhaps there is some marketing edge to this surveying or it is related to some big research project.

Bonus well-being info: for occupations, doctors and then K-12 teachers lead the way and manufacturing-production workers and then transportation workers are at the bottom.

Forgotten infrastructure of the day: locks

Posted on by

Business and transportation in the United States would be a lot more difficult with locks to even out heights between different bodies of water. Here is a 50 second time lapse video of the first ship of the spring passing through the locks of Sault Ste. Marie, Michigan.

Water traffic within the United States might not garner much attention compared to rail and truck traffic (perhaps except during seasons of drought) but it still accounts for a lot of goods and has a historic role in opening up the interior of the United States. For example, the connection between the Great Lakes and the Mississippi River through a canal and several rivers was critical in leading to the growth of Chicago.

Differentiating between playgrounds and parks in poor versus wealthy neighborhoods

Posted on by

Researchers in recent years have looked at different amenities in poor versus wealthier neighborhoods, things like pawn shops, payday loan stores, and grocery stores. But what about parks and playgrounds? Here is a summary of a new study:

A recent study, published in the journal Annals of Behavioral Medicine, looked at the amenities in 165 parks in the four-county Kansas City metro region. Low-income neighborhoods actually had more parks per capita (perhaps a result, the authors suggest, of the fact that minority communities in the area are largely located in the older urban core where more parks were once planned into the city’s layout). Parks in predominantly minority communities were also more likely to have basketball courts.

But the researchers also found that these same parks were less likely to have aesthetic features like decorative landscaping, trails and playgrounds. As the authors explain:

These findings are problematic because playgrounds have been shown to promote increased [physical activity] intensity and healthier weight status among children. Areas of low [socioeconomic status] are perhaps the neighborhoods that need playgrounds the most due to the increased likelihood of those areas having a higher prevalence of youth who are overweight or obese.

These findings also suggest one simple strategy (among many needed) to address health disparities in low-income communities in any city: Make sure public parks seem like places a 7-year-old would actually want to spend the day.

Parks are complex spaces. Jane Jacobs discusses them in The Death and Life of Great American Cities and suggests they aren’t necessarily good – like other areas of a neighborhood, they require care and benefit from a mix of uses and people on surrounding streets. Parks can be planned for but also require physical and social maintenance.

I was reminded again of some of these different amenities in a recent visit to a community gym in a nearby community. It was a busy weekday evening with a variety of activities taking place: the large room with aerobic and weight equipment was packed, the gym with gymnastics had a small class in there, and then there was another larger gym space. It was an open night for basketball with two possible courts. However, one court was being used for about 10 ping-pong tables and the other for basketball. In other words, how much are park amenities, like basketball courts or hiking trails, tied to the race and class status of the neighborhood?

Illinois Governor suggests freezing money provided to local governments from Illinois income tax

Posted on by

Economic times are tough so Illinois Governor Pat Quinn has floated the idea that the state limit how much income tax is shared with local governments:

Gov. Pat Quinn has proposed that the state bolster its own troubled finances by freezing the amount of state income taxes shared with local governments at 2012 levels, which could cost some towns hundreds of thousands of dollars.

Quinn estimates the plan would generate an additional $68 million for the state budget. Because income taxes are disbursed on a per capita basis, the impact to local budgets would be $5.30 per resident, according to the state.

But the Illinois Municipal League estimates the impact would be more than twice that — a $148 million payday for the state, but an $11.50-per-resident cut to local budgets…

Illinois’ income tax, enacted in 1969, was meant to be a shared venture between the state and local municipalities, said Larry Frang, executive director of the Illinois Municipal League. Both the state and local governments alike felt the effects of any dips or spikes in revenue, he said.

This is not a huge surprise given the issues of tax revenue facing various levels of government. To some degree, local governments should get used to this. Plus, if local government is at least partly about local control, then how much do some communities want to rely on money from higher levels of government anyway? On the other hand, raising property taxes and introducing new fees is not attractive to local governments.

Thinking more broadly about the connections between local and state government, does these ongoing economic issues suggest the relationships between the two bodies are more fragile than we might think? When times are good, this probably doesn’t come up much. What recourse do communities, or lower levels of government, have to fight back if the higher level of government, like the county, state, or federal government alter the existing relationship?

More women now sole breadwinner (23%) or earn more of two working spouses (28%)

Posted on by

USA Today takes a look at recent Census data and finds women’s status as breadwinner continues to grow:

A USA TODAY analysis of Census Bureau data reveals a revolution in the traditional roles of men and women that extends from college campuses to the workplace to the neighborhoods across this nation. Today, when one spouse works full-time and the other stays home, it’s the wife who is the sole breadwinner in a record 23% of families, the analysis finds. When the Census started tracking this in 1976, the number was 6%.

Just as telling, wives outearn their husbands 28% of the time when both work, up from 16% 25 years ago. This means the wife is bringing home the bacon — or at least more bacon than her husband — in more than 12 million American families.

Facebook chief operating officer Sheryl Sandberg (author of Lean In, which explores workplace biases) and Yahoo chief executive Marissa Mayer (who limited the company’s telecommuting policy) have stirred debate about the complex choices occurring as women push themselves higher and higher up the economic ladder. The earning superiority of women over men isn’t the rule, but it is increasingly common.

This is a consequential shift.

I do think the rest of the article illustrates the difference between journalism and sociology. The article goes on to give 12 brief overviews of couples where the woman is the primary breadwinner. They try to break down a few patterns. However, after seeing these statistics, I want to see more data (12 cases doesn’t cut out) and a more rigorous analysis (more statistics over time, more social forces that these changes affect).
