Peace of mind (knowing that your partner is ok) can significantly reduce stress and increase quality of life.
Even if the device can’t give an alert soon enough to do anything, just looking and seeing that they are ok this morning can bring a sense of peace, and that’s worth something.
It sounds like your driving instructor wasn’t any good. A good driving instructor will never put you in a situation that you are not ready for. They never should have allowed you to get a licence until you felt safe.
If you feel like you’re not in control then you’re right - this accident is proof of that. If you want to try driving again, I highly recommend getting a good driving instructor first - one who won’t put you in situations you can’t handle.
If you can get everywhere you need to without driving, then you can save yourself a lot of money by not paying for a car, insurance, or registration.
You always have the right to say no, and you can always say “not now”. Maybe wait a few more weeks before making a decision.
