The obvious flaw is that 3000+ lb vehicles are mixing freely with humans who weigh more than 10 times less. Due to physics, there are guaranteed to be numerous deaths and injuries. Cities should be redesigned for generally much smaller single passenger autonomous vehicles and complete physical separation between pedestrians and vehicles. Not saying it's easy, but it is feasible in the long term if people are eventually able to see this obvious structural problem.
