If you don't follow Tesla you might not know but they upgraded software on the existing Autopilot cars to give the radar equal weight in decision making as the camera. There's a long post I made about it but basically they were able to get higher resolution data from the radar thanks to Bosch supplying new drivers and combined with crowd sourcing data from the roads (the cars all report false positives back to Tesla who then geo-fences them and marks them) they were able to vastly improve the system.
One of the benefits was that now instead of seeing the car in front of you, Autopilot can also see the car in front of that one by bouncing the radar under the car in front of you. So in theory the car in front of you might not see that the car in front of them is completely stopped and your car will respond to the stopped car two cars up while the car in front of you never sees it and barrels into it.
I've had this happen in practice too, though not at speed. A few times on the expressway in moderate speed traffic (20mph) I've had the car in front of me not see the car in front of it slowing down but Autopilot started braking my car. It's neat tech and this system probably isn't even a fraction as nice as the eight camera setup they're shipping in cars now.
