I believe these have existed in vehicles for quite a while and have been used as evidence for/against the driver. According to [1], 85% of all vehicles in 2010 were expected to already have these things installed.
Thank you, until now I was totally unaware of such systems.
But good to have things stored locally than to have them uploaded anywhere to then be used for some analysis (puah, probably a point to be discussed).
Personally I'm OK if used for&against the driver (from a technical perspective, not as souce of abolute truth) if the duration of the recordings are short.
In a defensive driving course I took in the prior decade, the instructor informed us that these collect data in a rolling 5 minute window until an adverse event occurs.
