I would have to agree with Southpass! Except he most likely would have both feet out of the vehicleo or like southpass indicates up on the hood! Due partially to the aussie "laid back she will be right" attitude and just in case he needs to jump from the vehicle in an accident.
Have heard of a driver on one of the bush tramways in victoria performing what he called his evacuation procedures. What he would do while the loco was travelling along. He would jump from the train swing around a handy tree and back into the cab!
I have also heard of a rail vehicle (funnily enough on the same line) which was a converted car. And it was making a run along the line and came over a hill and the bridge had washed away. The unfortunate part was the railcar had no brakes. So every one jumped from the vehicle! The driver jumped out and grabbed hold of the back of the rail car and was able to pull it to a stop before it fell into the creek!
So it could be safer for this driver to have one leg in and one out! Just in case!
As I have seen it written before. "There is a prototype for everything!"
