I learned by watching and by playing video games.
Seriously, when I was six, I already understood not only that when the engine made a certain sound you had to press the left pedal, move the lever in the middle, and let the left pedal back out, I also understood when and why. That puts me a step above many people on the road today! By ten, I knew many of the rules of the road and how they sometimes superseded/broke the law. Nobody taught me those things either.
As for playing video games, understand that some of the racing games are quite realistic, and even without them, it doesn’t take much to learn the difference between FWD, RWD, and 4WD/AWD and how they handle differently under different conditions like rain, snow, or ice. Understeer and oversteer are simple physics though watching people trying to drive in Seattle in the winter makes me think some people are simpler and video games are a good way to get experience with them without causing actual damage/injury/death.
However, I got my license rather late in life’ I spent my late-teens and early-20s in the Navy and thus had no need of a car or a license. Well, no need that couldn’t also be met by a valid Military ID. Given the parking situation for E-6 and below on many bases, a car would’ve actually been worse than useless. Wen I finally got one, I didn’t even study , nailed the written with a 20/20 score, and the only points I got dinged for on the road test were for not adjusting the mirrors before starting the car. (No need to since I drove that car there so they were already right, but the proctor didn’t believe that :p)
