Would you buy a car that had a camera pointed at you constantly, recording for use in an accident investigation, uploading periodic short videos to Tesla for use in their training data?
Absolutely yes, because I don't drive like a stupid idiot—and if I ever did I'm not going to deny responsibility.
However I don't see why having a camera pointed at my face necessarily means that Tesla have to willingly provide information to insurance companies. As long as it is only available to law enforcement after being granted a court order, I'm fine with that.
(Note: I do not live in the USA. I trust the law enforcement in my country. My answer would be very different if I were in the US resident. I've heard enough about law enforcement in the US to know that I'd never live there, and if I did, I wouldn't ever trust the police.)
Firstly, no-one has a right to drive distracted, any more that they have the right to drive drunk. Secondly, monitoring the attentiveness of a driver, as a backstop for weaknesses in the automation, does not require recording. Thirdly, this might be a good point to remind ourselves that this is, according to Tesla, a beta-testing program. The goal should be to get to the point where constant driver attentiveness is not necessary, but until that is achieved, additional safety measures are justified.
