Andrej Karpathy claims to stand by that decision: https://youtu.be/_W1JBAfV4Io?si=QUceD5ZG0j_hclHP&t=39

"Did you agree with your egomaniacal boss who thinks he is a brilliant engineer and programmer when he made one of the biggest blunders, or did you know better?"

0 projection or prejudice being done here, you come across as perfectly rational.

They are trialing a radar again in the S, but from their marketing it doesn't look like it's a clear benifit yet

I would compare them to other companies: they’re not going to lightly outshow their own products since that both affects sales and increases the odds of a lawsuit on behalf of everyone who bought the older models under false advertising. It’s more likely to end badly in court if the lawyer can say everyone else in the industry got this right but their clients vehicles will never get the promised features because they lack the necessary hardware.
