@LiberalLibrarian The only way flying cars happen is if you take human operators out of the equation. You've seen how people drive. No way do you add a third dimension to their inability to pay attention. Centralized control. So yes, there will be flying lanes. :)
@ianthealy Seriously, that's what I was assuming. Everything would have to be networked.
Wasn't the "insanity" of manual control one of the tropes in both the "I, Robot" movie, and "Minority Report." (I know it wasn't in the Asimov book, because they had people movers, but I've never read Minority Report).
