They probably got downvoted for wrongly assuming the technology doesn't deal with rain or snow, and then presenting that assumption as fact. It works great in rain. Snow, I have less experience with, but it seemed OK during a winter vacation with snow.

With neural nets, a lot of things just get learned. You don't have to specifically address them to get great progress. I'm not saying snow is 100% solved, and yes specifically addressing aspects like snow in the future will help make it even better, but autopilot has worked pretty great so far.
