I agree with your viewpoint, while we should be protective of our children we should not be over-protective and should teach them the skills that are essential to their future. And in your case that is to teach him to drive a two-wheeler and a car. In my case I pushed my son to go to driving school to learn to drive, he didn't want to learn to drive. Then I pushed him to use my extra car that I had (for free, except he pays insurance and registration) instead of sharing a car with his grandparents like he was doing at first. I think those things are essential for children to become independent adults.
For which they will thank us later, for sure.
