I would rather that when my DGC learn to drive they have a black box watching over them for at least a year. There have been far too many young people killed in road accidents, usually related to speed, around here. There is no divine right to drive, and anything which makes it safer for young drivers (and the rest of the traffic on the same road) is, IMO, nothing but good news.
However, I do agree with you, quizqueen about smart phones, alexa and also smart TVs. The information they seem to be able to gather does nothing towards keeping anyone safe, just lets them target advertising at you!
