>Lidar has no problem with snow, only when its _snowing_. However, if visibility is reduced, a pure visual approach is going to be even worse.

Good thing Teslas have radar...which penetrates falling snow.

>Musk made a mistake, and he's spending billions to prove that he never made it.

People drive fairly well with only visual sensors (eyes). That is proof of concept. Lidar seems like overkill.
