In a safety critical system, I don't like hearing "we don't need x, we can get by with just y". I like redundant systems, especially when one may do better in certain conditions than the other.
Now I am not so sure anymore.
Looking at the beta UI in the car while it is driving, I am impressed with how well it detects everything. There are examples in dark and even areas with leafs covering parts of an unmarked road. It doesn't look at all like the detection system is struggling.
The only thing is, that things seem to "float" a bit, or cars and pedestrians disappears when going behind other cars and reappears again on the other side. The sides of the road also seems to float/shift a little bit from time to time.
I wonder if they are not using a temporal filter of some sort (like assume a car continues in the same trajectory when goes behind another object), or if the UI only displays an "unfiltered" value.
In any case, I still haven't seen examples where the cameras didn't pick up anything relevant/critical.
