> in the $25K to $35K range now Why are you buying a new car? You can get a very decent car for $8K. And if you did buy a new one, you don't have repairs and maintenance expenses. > The combination of public transit, on-demand self-driving cars, better city design, telecommuting could allow us to redirect that capital more productively. Doubtful. Public transit usually takes 3 times as long, so you are wasting human time in exchange for capital (there's a reason people buy cars - it's not because they want to waste money). Self-driving cars will never happen, and city design can't help all that much. From your list, only telecommuting can help, but only if you do it full time. (Also your dollar estimate assumes all new cars, which is far from accurate.)
