I think the fact he's waited so late in the transfer window to hand in a request, shows he's not really sure he wants to leave, otherwise he'd have handed the request in weeks ago. Not good for him to make a deal in a hurry.
You're only considering the chance of being hit by a car. Add in the 50/50 chance that a bus will hit you, and the same again for a truck, and its far more sensible to stay where you are.
They said during the show, that they'd all passed their ARDS (Association of Racing Drivers Schools) test. Once you've passed that, all you need is a medical (and some dosh) and you can get a licence. Ms Dinamite is quite fit, so I assume the medical was no problem for her.
