Get the tell-tale and drive it. America is very populated and the OMG worst case is you put it onto a transporter and catch a partial flight home.
The best case (which I did this past summer) is you and your wife get some great times driving across the country in an amazing car, create some very cool memories and 'unplug' from your life for a few days. Don't check your email more than once every other day (if at all) and you'll cherish the memory for the rest of your life.
