>They can even “look”under the car in front of you and get a return for the next car in front of them, to better predict braking needs.

I miss that feature the most, even though my Tesla has radar it has been disabled via software. With that feature I would know if the person immediately in front of me was going slow, and I could/should overtake or if there were a line of cars in front. I used that feature daily, made me feel a bit superhuman.
