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.
I said “The rest of the SDC industry uses 4D radars” in a follow up comment, which clarifies I don’t mean car manufacturers.
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.
Well, until these are actually adopted by a car company and out on the road, any claims about performance are meaningless. Your original comment implied Tesla chose to use inferior tech compare to the market which is not true in the slightest.
