Well, of course, if you could make it better - sure, go ahead. Do you think I like driving 30 mins twice a day? I'd rather spend the same time in a bus reading a book. But I don't have such option and do not foresee it happening anytime soon. You can say "we should" as many times as you like, but in reality it's not happening - and I'm not sure it's even feasible to cover an area of San Jose size with adequate public transport and keep the costs reasonable. But if you know how to do it - sure, let your plan be known to the San Jose city council, I support it a lot. I'm sure amount of cars would decrease once you pull it off - I'd gladly give up my daily commute if I had an alternative. But not before the alternative is there.
