Once again I offer NYC and it’s ten year change from horse and buggy to cars. Electric cars may present a whole host of different problems, but just because something seems challenging doesn’t mean it can’t or won’t happen. There was a time when people believed that cars would always be a rich man’s toy until Henry Ford, for example, decided to prove them wrong. Don’t forget also how quickly we connected California to New York City and the whole of America by Eisenhowers highly successful plan to build highways.
