NeilBlanchard -- I'm going to have to watch that a few times. I even took notes. He has a good take on the engineering. With a disruptive technology that (with Google's help) makes mass transit go away because it is too expensive.
Did you notice he mentioned "the *Volkswagen* of the 21st century"?
3rd-party aftermarket upgrades to a BMW 3-series level of car. [he's a racer] He wants to sell suspension upgrades for you station wagon so it gets 60mpg. I need to watch that one again.
I like the 'breakaway' argument in favor of open wheels.
