Because most people's trips are the commute and they haven't been given more time and money to go and road trip more. That isn't analogous to computing though. People do the same things broadly they've always had with computing, but we've figured out how to create a system where your computer today running microsoft word is 100x as powerful as your computer in 1995 also running microsoft word and you feel the need to upgrade your hardware every couple of years so you can continue running microsoft word. It is the perfect model for exponentially dumping raw compute power into the void to perpetuate value creation. It will not stop in our lifetimes I expect. In 25 years our computers will be 100x more powerful still and we will still have MS word.
