"Our estimates indicate that two-thirds of people who buy hybrids were going to buy them anyway," said Chandra. "So for the majority, rebates are not changing behaviour — they are subsidizing planned purchases."

I believe the same can be said for cash for clunkers. If you take advantage of it, you were probably planning to get one anyway.
