They can't, without your consent. The problem with google & fb is not primarily that they will share their data with 3rd parties (without your consent). It's that they will use it against you. E.g. they'll show the right adverts to nudge your behaviour in directions you may not want but for what they are being paid for. E.g. imagine a political party wanting to efficiently gain new supporters by converting those who are most susceptible. FB and google will have a lot of information about a lot of aspects of your life and they can sell services (not the data!) to interested parties based on that knowledge. Tesla will just know about your driving habits and probably won't be able to sell anything based on that. It's a huge difference. Law enforcement, now that's a different story. You'll probably want to keep the privacy laws of your country strict and not allow peeking into the memory or recording of your car too easily.
