Really? It can't see much
Really? It can't see much better than you can. I just drove home today in torrential downpour, the kind that brings a 75mph freeway down to about 40mph for most cars. You couldn't see more than 75-100ft ahead. The eyesight system turned off briefly a few times for about 20 seconds each. It's not meant to drive for you, it's to aid your driving. But if your human vision is impaired by extreme weather, why would you expect some cameras to see better?
