Im with theBob on this one. As for how to regulate: retest everyone every 5 years for whatever liscence. This once and done is crazy so much has changed since this guy got his liscence. Lets see 86. That means this guy was possibly issued his liscence in 1930 something. Do you think anything has changed since then? In 1933 there were still cars on the road where the throttle was a lever that you worked with your hand. Maybe that is what confused him.
