The United States depends on goods shipped by truck. This comes at an environmental cost:

According to the Department of Energy, even though medium- and heavy-duty trucks account for only 4% of the vehicles in the United States, they consume 25% of total highway fuel and create nearly 30% of highway carbon emissions. Stricter standards on smog-forming emissions on trucks will take effect in 2027, which could force companies to turn to electric versions such as this Tesla fleet.

Since trucking is essential, even small improvements to gas mileage and emissions could go a long ways. I am not sure that having full fleets of electric trucks or even autonomous electric trucks in a few decades time would look that futuristic but it sounds like they could help.
