The idea that everyone has their own "public transportation" (a computer chauffeur) seems lacking in foresight.
I suspect, but don't know, that buses are safer still? (Not aware of any airbags triggering, ha ha.)

How so? As you increase the density of stops in a bus network and increase the rate of arrivals, there will be fewer passengers per bus, going on journeys that approach the fastest they could be. Why look at the one thing that has a really good chance of "fast, cheap and good" and say, "lack foresight?" My dude, it's the only game in town!
