Consumer reports recently added a privacy rating to their car ratings. I glanced at it a little last year. I think it rated if you could opt out and the reach of the sharing.
I do have to say that I’m generally disappointed with the discussion on this topic every tine it comes up. The majority of responses go contrast to the question. “Don’t buy a car” or “fix up a junker” are generally not helpful if you’ve already decided that your top priority is to have a newer car. Another thread actually recommended to move to another country where you could walk everywhere. Seriously.
Most often a car purchase is a complex decision making process where you need to weigh multiple, often conflicting priorities where privacy is only one aspect. I get the impression that if people followed the advice of the majority of these comments, they’d be living in a tent off grid, hunting for food to stay alive, but living their privacy dream.
I saw a show about self defense for women in NY city. The instructor said to always carry a sucker. One of those tootsie pops or the like. If in trouble, hold the ball in your hand, turn the stick outward, between your middle and ring finger and punch at something soft and fleshy like stomach or face (eyes, mouth). It’s nice because it works everywhere. Even the TSA will let you board a plane with a sucker.
