But it can be done better with more sensors. Why handicap the technology? It seems to me like the compromise isn’t worth it here.

My phone can take my face scan in a room that’s pitch black, because it uses infrared sensors and a projection of dots. It’s able to check who I am, regardless of the natural light in the environment. If that technology was limited to “only a camera” it would be way worse.

A camera is cheaper than LiDAR. But it’s also less capable.

As best I can tell. Other cars just use a dedicated infrared sensor to detect the water? Seems like a weird corner to cut. Seems like tesla cut those in favor of just having other cameras attempt to fill in? But seems like that isn’t working.
