It’s far easier to get to the grocery store without hitting anything with the car than it is to, say, pass the first level of Super Mario Bros.
Then why don’t we let kids who can beat Super Mario Bros in their sleep (and thus from your perspective have demonstrated the skill required to learn how to drive) drive cars?
Again just because it is easy to aim the steering wheel and press the gas peddle doesn’t mean that every time you so much as drive to the grocery store and back you aren’t literally doing the most dangerous (mandatory) activity in most adult’s lives (both in terms of risk to yourself and risk of killing or hurting others).
