I am sorry for the child, but what in the name of God was that man thinking letting a 10 year old even get near the wheel of a car or truck. I would nominate him for a Darwin Award but he has already reproduced.
The child is going to need a lot therapy and relatives that tell him he's not at fault.
Farm families have been doing such for many decades with relative safety. Of course, wise farm fathers insure the child is well trained AND THEN STILL WATCHES ALERTLY IN HAZARDOUS SITUATIONS.
