I don&#x27;t think it matters which one is better - each has a niche to fill.  I would much rather hop on a train and be in LA or Seattle in an hour, than get a self-driving car and be there in 6+.  But for short distance, cars or a slower, more traditional public are the better option (mainly because you can&#x27;t have high-speed lines to carry people a few blocks at a time)
