Not only that, but took out the radar, which while it has its own flaws, would have had no issue seeing the train through the fog. While they claimed it was because they had "solved vision" and didn't need it anymore, it's bullshit, and their engineering team knew it. They were in the middle of sourcing a new radar, but because of supply chain limitations (like everyone in 2021) with both their old and potential new supplier, they wouldn't continue their "infinite growth" narrative and fElon wouldn't get his insane pay package. They knew for a fact it would negatively affect performance significantly, but did it anyway so line could go up.
While no automotive company's hands are particularly clean, the sheer level of willful negligence at Tesla is absolutely astonishing and have seen and heard so many stories about their shitty engineering practices that the only impressive thing is how relatively few people have died as a direct result of their lax attitude towards basic safety practices.
