> Driverless cars are useless, cars - as a class - spend 80-90% of their time parked You're talking about passenger cars? I'm agree that they're quite inefficient. But we don't need autonomous vehicles to solve that inefficiency. We already have perfect solution -- public transport.

There's a tipping point in population density where current modes of public transportation are not the appropriate solution. Buses, trains, subways and even cabs barely work in most suburbs and don't work at all outside of that. Autonomous vehicles would provide a mechanism to extend the range of these services by reducing the costs of dwell time between rides and deadheading for pickups.

  Yes, but does dwell time really matter? The EOL of a car is usually determined by the number of miles driven, not how long it stands without moving. On the other hand, if the (autonomous) car is not waiting for you, it needs to drive to you, driving even more miles (and wasting your time).

    For private ownership no, I'm talking about its potential use for public transportation.

  Uh, I live in Switzerland where buses and trains work in the entire country and in most rides - yes even country side - offer time comparable to driving by yourself. So instead of claiming something doesn't work at all, the US people could just look outside their own borders. I totally understand the political climate is very different between countries, but the technical solutions do work.

    Switzerland has 8 times the GDP per square km as the US. Six times the population density and 1/90th the total road network. Switzerland has ~72,000km of roads, my local school district puts 4,500km on their bus fleet every day just picking up students. I agree that there are no laws of physics preventing it from occurring in the US.

  > Buses, trains, subways and even cabs barely work in most suburbs and don't work at all outside of that It looks to me like mentality problem, not technology one. IMO, changing mentality of people(to refuse from excessive lifystyle/showing off) would be more beneficial for society in long term.
