David Levinson, a civil engineering professor at the University of Minnesota, argued in a recent paper that we’ll see a Cambrian explosion of new vehicle forms that are designed for specific tasks.

“The fleet will have greater variety, with the right size vehicle assigned to a particular job. Today there is a car-size arms race: people buy larger cars, which are perceived to be safer for the occupant, and taller cars, which allow the driver to see in front of the car immediately in front of them,” Levinson said. “Both of these advantages are largely obviated with autonomous vehicles. The car-size arms race ends.”
