Short answer to the OP is... probably not.
However there are some 25 or 35 year olds who probably shouldn't be driving. How many people are driving around chemically lobotomised on prescription meds like amitriptyline? The only way to properly "police" (in the wider sense) is a fitness and competency test for all drivers every 5 years (including drug screening). However that would bring cries of outrage from pretty much all corners of society, but in particular those in rural areas who have little choice but to drive even if it's just to buy a loaf of bread or get their amitriptyline...
