This is almost like an urban legend come true.
Many people in Europe and other countries have heard the story about someone willing to give them a free car to drive across the USA. I always tell them that this is not a very common occurance. Anyone that wants to transport a car across the USA, would normally pay a shipper, that has insurance and a reputation to take the car for them. If they get someone to drive the car, they are faced with the dilemna, of how to I know I can trust the driver before I give him my car? and, Will my insurance cover the damage if he wrecks my car or perhaps wrecks someone else's car and causes injury?
There are a few companies that arrange such shipping of autos. They apparantly find drivers and insure them before they take someones car across the country. I believe they charge the car owner some fee for doing this. If you use them, then the question becomes, can I trust this company?
Before you hand your car keys to some stranger, you must consider, what happens if this person, causes an automobile accident in Kansas City, robs a bank in Chicago or commits an act of terrorism in Cincinnatti? Can I be held responsible?
