>At the very least adding sensors I don't have access to will give me assurance the car won't drive into a wall with a road painted on it.

This is as relevant as self driving cars not being able to detect anti-tank mines. If you want to intentionally cause harm, there are far easier ways than erecting a wall in the middle of a roadway and then painting a mural on it. If you're worried about it accidentally occurring, the fact that there's no incidents suggests it's at least unlikely enough to not worry about.

>Aggregate statistics about safety aren't going to make me feel emotionally stable when I am familiar with how jerky and skittish the driving is under visually confusing driving conditions.

Sounds like this is less about the tech used (ie. cameras vs lidar) and how "smooth" the car appears to behave.
