I don’t like the spying aspect but it is unironically true that if you slam your brakes at every red light you are driving in a dangerous fashion. It’s more so about the pattern than a one off event though.

I mean without getting into the privacy nightmare piece, frequent hard braking probably means you have a habit of following too closely, or not paying attention to potential hazards and covering a brake. So I don’t think the car manufacturer should supply it but also think it would be good to let the person with the habit know so that they can learn to be a safer driver?

Nah bro if it’s the choice between raising insurance cost vs killing people + jail time for manslaughter + eating the guilt for the rest of my life, i’ll take the insurance.

Also wth america your capitalism and your priority is wack.
