Free car to travel in Canada and USA

Here is an interesting website:Auto Driveaway Company for those of you who want to drive across Canada or USA and have a car for free. The principle is that you have to drive a car from an agreed point to another in order to transport the car for its owner. You only pay for the gas and also have time restrictions to do this but it may be a great way to visit some places.
I checked the offers and found a deal from NYC to Los Angeles driving a Lexus. Another deal was proposing a brand new Toyota Celica 2004.
