Clark has long been a fan of the Smart Car, a Mercedes Benz-produced 2-seater that gets great fuel economy. He was all set to buy one, but then he saw the crash-test ratings from the National Highway Traffic Safety Administration.

It's perfectly safe for the driver and received the highest rating of 5 stars. But it isn't safe for passengers, earning only 3 out of 5 stars. As a parent of 2 small kids, there's no way that Clark is going to compromise the safety of his children in a Smart Car now.

(Editor's note: The day after Clark spoke about this, the highly respected Insurance Institute for Highway Safety gave the Smart Car its highest rating. Clark says he'll defer to the findings of the IIHS on this one.)
