Definitely not unaccompanied. I’m at the point now where I don’t even believe they should have access to vehicles. In general, there really is no need for more than one safe reliable vehicle for each household. Even if you allow your wife to leave to do the grocery shopping and shit, she can get plenty done from 5pm-8pm if need be. Just 15 years ago, I would have said I was nuts/extreme, but it’s pretty obvious I’m not now.
