The author compares the safety and throughput of self-driving cars to trains, where they should have compared against regular cars. The problem with trains is the infrastructure isn't there and will not happen because it's impractical in an already developed metro area, and even if it magically happened the longer travel time would cause most people to still opt for cars. Self-driving cars will reuse the infrastructure that is already there and use it much more efficiently, so they are definitely a significant improvement.
- goodcanadian 11y agoYou sort of have a point with the infrastructure argument, but I'm still getting a bit tired of seeing it. The roads didn't just spring into being. A great deal of money is spent on new roads and widening existing roads every year. If half that money went to rails, we would very quickly have an extensive and efficient rail system. As for space, one set of rails takes up about the same space as one lane of traffic. There are plenty of places where a lane could be taken off each direction of a freeway, replaced with trains, and the total throughout would be increased drastically. Self driving taxis could be used for the last mile in those cases where transit really is too far from home or work.
