Karpathy addressed this question at the time:

Of course he was working for Tesla back then. His opinions might be different today given that Elon is no longer signing his paycheck.

His opinions aren’t much different in interviews I’ve heard since, although of course that doesn’t mean he’s completely unbiased now.

What a weird argument by Karpathy. He has a degree in physics. How does this dude not know that radar can see things not possible through camera vision. That argument there doesn't make any sense. That there's supply chains and things break and this makes it unsafe? Well that's true for every single bolt, every nut, ever little thing. I understand a drive to simplicity but you can't just throw fancy words in there like entropy while ignoring the literal physics that says camera + radar is less entropy than camera no radar. There is literally more (unique!) information available to you!
