I agree, it could definitely be a situation where owning a car is like owning a plane. Sure, some people do it as hobbyists, but why would you when there are extremely efficient (computer operated) and inexpensive (no taxi driver, 100% uptime except for filling up/charging) taxi services that can take you around. Especially as more people use them (thus reducing wait times) I could see taxis being usable/profitable even in the suburbs.
