What If Auto Garages Worked Like Public Schools?

Imagine a world in which all kids were sent to auto mechanic school for the first few decades of life.

Some percentage of them, those destined for a future with cars and mechanical problems, would love it. It'd be a great fit for them. They'd spend their time focused on the skills they enjoy and that will bring them value in their careers as mechanics.

For most, it would be wasteful and annoying. They'd spend years and years being prodded into memorizing and repeating facts and tasks that they don't care much for and that bear no resemblance to what they'll do for a career.
