My copy of the Bill of Rights must be out of date, I cannot seem to find the right to drive a car anywhere.
Other than the "Title and tag at point of sale" the rest of the restrictions on cars are only if I want to use it on a public road. I can use it on private property and at the track without any of those other requirements. I can buy any car I want and can afford. Off of public roads, I can possess and operate any car I want without restriction, without a license, without insurance. I doubt guns will ever be as unregulated (at least in MA) as cars are.
Also training is not required, you can wait til 18 to just take the test, and health requirements is pretty much just a vision test.
