total BS, you birds continue to spew the same rhetoric over and over.   don't you understand that cars take space, no new roads or highways are planned to be built except in new developments.  if the pace of car ownership continues, there won't be space for people to drive and park their cars at work or while shopping.  even self-driving cars must deal with traffic and traffic signals, they will be stuck in traffic like all other vehicles unless they can fly.  trains will never become obsolete, that is why many cities in America and worldwide are continuing to build railways.  we will have driverless trains but they won't be stuck in traffic on roads like your driverless cars.
