Creating a car that's as good as (or even slightly better than) a Toyota or Honda isn't going to get people to buy American anytime soon.
Instead, US auto companies have to create revolutionary products. (And ones that are so elegant and beautiful that everyone wants one.) That's what Apple does in the consumer electronics industry. It enjoyed its best quarter ever at the end of 2008.
The auto companies need a Steve Jobs-type in charge. Someone who's instinctively tapped into what Americans crave.
