IQ minimums to operate a vehicle?

Mine is one of those "general reference" commentaries about the smarts level of average drivers.

I want them to be bright enough to understand how to use blinkers, understand proper stopping distances, know how to safely change lanes... real basic stuff.... was thinking perhaps a basic smarts IQ test would help sort out who should get to pilot a 3000 LBS vehicle while staring at their phone.

The skills for NASCAR, which comprises extremely talented drivers and tech support, are totally different from the defensive skills required for surviving in mundane traffic. NASCAR drivers may be on the radio to their pit, but they are not playing with their cellphone. NASCAR drivers are wearing HANS devices to prevent neck-break in a crash. They are wearing NOMEX suits to protect them from fire as a result of a crash. NASCAR (and other racing) drivers are a million times more aware of their mortality than the assholes you see on the street, and they drive accordingly. Everything in a NASCAR driver’s environment reminds him that he could die. Joe commuter has no such reminders.

NASCAR is by no means my favorite form of motor spots, but I have tremendous respect for it, and none whatsoever for ignorant trivialities like the gadfly OP.

what about maybe ALWAYS having a written test every time you get license renewed, with many trick questions to see who is bright enough to pass:

When needing to change lanes, pick the best option:
A: just swing on over, whoever is behind you that is their problem
B: check rearview and blind spots, begin signaling, check for 3 car lengths space for safety, look behind again, change lanes
C: set your cell phone down on your right leg so you can keep reading it, steer with your left leg, signaling is optional, keep left hand free to flip the bird if anyone honks

again... unrelated.... why?

I would PAY for advanced driving training and lower insurance! Brilliant idea! I already know lots of evasion and proper attention from being a motorcyclist

‘Insurance companies could offer “advanced driver” policies to drivers willing to undergo more training.’

My drivers license is a commercial drivers license (CDL) and I have always thought insurance companies should take that into consideration on private policies.
