Tesla has sold over 500,000 cars with AP.
These cars send data back to Tesla; Tesla has over 1.2B miles of data.
Is is used to improve AP.
I believe the data will be used in their soon to be released insurance business.
Safe drivers will get better rates...
As far as reaction to being cutoff, AP is probably better than most drivers. The cameras are on all the time.
As far as this driver goes, faking or not, he is an idiot who should be held responsible.
