You've GOT to be Joking

Bill Gates and the president of General Motors have met for lunch, and Bill is going on and on about computer technology. "If automotive technology had kept pace with computer technology over the past few decades, 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," says Gates. "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. Why haven't you guys kept up?"

The president of GM smiles and says, "Because the federal government won't let us build cars that crash four times a day."

Ba dum dum.

Emphasis on the "dum", maybe?
