I drive with a six car gap and even that was a close-call when someone had a contact about 3 cars ahead.
The good part is that if the car in front of you flashes the brake lights, that seems to trigger the braking. And some of the newer cars blink hazards automatically when braking hard.
My Subaru is also vision only (Eyesight), which also has the cameras too close together (in my opinion) to detect a car ahead braking, but it did not slow down quickly when facing a stationary car facing the wrong way around (my feet went down before the car did anything).
All of these need more parallax, at least better than a human to do this well. But they do react to visual cues like brake lights and hazards. Though sometimes, it sees a motorcycle nearby as a car in the distance simply due to the lack of parallax.
"more sensors good" is not always a good thing, when the sensors disagree with each other. Sometimes more sensors just mean more corner cases and braking at bridges throwing shadows on the road.
So just removing something feels wrong, when I don't see them improving the thing they're putting more eggs into.
I think this is where Tesla is not credible right now, when they say they're improving something in the car, but it is a thing I cannot see, check, confirm or test.

When they disagree, one of them is wrong. Would you rather have just the wrong sensor or both the wrong one and the good one as inputs to decide what to do?
