You only need a valid photo id to register a vehicle, but to drive it you need a license.
Saying You Can Own A Vehicle But Can't Drive It Is Like Saying You Can Buy Beer But You Can't Drink It.
Where Is The Logic In That?
You can buy a gun but don't have to know how to shoot it, is that ok with you?
You can buy a piece of land but need a permit to build on it.
A parent can buy a car for their kid and the kid gets the license and drives it.
Owning a car and driving it therefore have no necessary correlation.
I'm sure they would sell beer to minors as long as they didnt drink it.
It's your interaction (driving ability) with other drivers on the road that is the difference.
