>If only they had cameras in the cars so while they are applying the brakes when you are on the interstate they can collect that classic picture of horror on your face....
They already do. IIRC Model 3 has about 6 external cameras and one internal one. However, the internal one is currently disabled and isn't used for anything, which is a subject to change for when they decide what to do with it and push it in an update.
If you are looking for some wtf road videos, we are bound to see more of them soon due to the most recent update Tesla pushed. It added the "save on honk" option, which (if enabled) saves some footage right before the honk, as well as about 5 seconds after the honk. With how much spicy footage the sentry mode update has provided in less than a year, I expect nothing less from the "save on honk" update.
As a sidenote, it isn't as bad as it seems in terms of privacy, because all videos (on-honk ones, or manual ones, or the sentry mode accidents) only get saved locally on your HDD/SSD/usb-drive/etc (whatever you have inserted into one of the front USB ports).
