But that does get to the point. Maybe differentkinds of vehicles need different kinds of qualification testing. Would you trust your 16yo that just passed their driver's test in a sedan to tow a boat through town with an F250?
Fun fact - in most states a 12 or 13 year old can operate many tens of thousands of pounds of agricultural equipment “incidentally over a highway” or similar - which can be multiple miles between farm plots.
Same's true in the UK, but honestly they're some of the best drivers out there 'cause they've been hustling in farm equipment since they were tall enough to reach the pedals. I've seen farmers get picked up from my old local by their kids in a tractor before when they were too drunk to drive home.
