They removed the radars, they've never used LiDAR as Elon considered it "a fool's errand", which translates to "too expensive to put in my penny pinched economy cars". Also worth noting that they took the radars out purely to keep production and the stock price up, despite them knowing well in advance performance was going to take a massive hit without it. They just don't give a shit, and a few pedestrian deaths are 100% worth it to Elon with all the money he made from the insane value spike of the stock during COVID. They were the one automaker who maintained production because they just randomly swapped in whatever random parts they could find, instead of anything properly tested or validated, rather than suck it up for a bad quarter or two like everyone else.
