I've always kind of felt like the only way cars become autonomous is if humans are completely taken our of the equation. The cars need a standardized system to communicate with each other and be aware of each other with more than just cameras and lidar.

Which at that point, busses with the same technology should be widely adopted... but I know how that goes...

There is an assisted driving feature that's part of the cruise control of my car. One part is the adaptive cruise control. The other is assisted driving (glorified lane keep) that screams constantly if my hands are not in the exact place the car wants them, or I'm looking head of the curve I'm currently taking.

Essentially the features that were meant to be guardrails need guardrails and the video evidence is just a bonus to the liability, like you said.

This is more along the lines of "cars less than 10 years old don't depreciate after they leave the lot" and not "wow all used cars went up in value"
