Mostly only because Tesla doesn't share this data outside of Tesla, unless they leak it to news outlets to make it look like the accident was all your fault and not Tesla's.

I point out tesla specifically because they had headlines about sharing camera feeds as memes. The Mozilla report clearly shows tesla is not an outlier, more like "middle of the pack".

Tesla is not the least bad. Do you have that footage sitting in your car SD card or in cloud without access? Tesla is middle, if not worse
