I'm confused. Is the only way forward private automobiles? Did the creation of the Department of Transportation ban the creation of transit? Americans choose automobiles because of zoning laws mandating massive setbacks and minimum parking requirements. There's nothing in the DoT or my state's DoT that mandates use of a car. It's all due to American city planning, which is driven by auto friendly city planning policy. So again, why is transit out of the question here? Self-driving cars aren't an incremental improvement away. We have no idea how many more deaths are needed to mature the technology. So why are we bending over backwards for it when there are proven solutions to move people without casualty? If self driving can innovate without casualty, then be my guest.
