Bill Gates is hanging out with the chairman of General Motors:

“If automotive technology had kept pace with computer technology over the past few decades,” boasts Gates, “you would now be driving a V-32 instead of a V-8, and it would have a top speed of 10,000 miles per hour. Or, you could have an economy car that weighs 30 pounds and gets a thousand miles to a gallon of gas. In either case, the sticker price of a new car would be less than $50.”

“Sure,” says the GM chairman. “But would you really want to drive a car that crashes four times a day?”
