You said “everyone else” besides Tesla uses 4D radar, and “that's why Teslas have poor performance like phantom braking”. But there are zero production vehicles on the road using this tech right now.
Given this post is about radar usage in self driving and how Tesla/Karpathy touts their capabilities, I compare them to other SDC players, not other car manufacturers who are not in the game. And their SDC competitors are running away because they have the newer 4D radars.
Only if you don’t consider Waymo, Cruise, Mobileye and others as Tesla competitors.
+1 to the other commenter (grandparent comment).
Radar has a range resolution and an angular resolution. Andrej completely omitted this fundamental aspect in his talk.
In my humble opinion, Andrej needs a real Radar engineer in his group before making such a statement in his talk.
Nobody can be smart for all topics, which makes all humble also.
