The "humans drive cars with just optical input" has become a weirdly tightly held misconception for Elon Musk, it's a core part of his personality where autonomy is concerned:

Humans drive with optical input, haptic feedback, and millenia of evolution to handle the decision-making and social skills required to handle a vehicle safely. No LiDAR or radar waves, sure, but I wouldn't say no if either were on offer!
The dumbest part? He developed this belief in ~2019. Lidar costs have dropped immensely since then, and are fast-dropping still. Any technologist who doesn't fucking suck knows that component prices follow that depreciation curve. So he's basically an old man shouting at a cloud at this point, it would be cheaper to fix the mistake, but it could hurt his personal branding as a guru.
