Visibility is an issue but sdcs have superhuman reflexes and have no fear or surprise. Ice isn't an issue, they'll be far safer from loss of control than humans.

The biggest issue in snow is neither of those. It is that humans drive very differently in a way that'd be illegal typically and that's challenging for sdcs. Learning that where the lanes actually are matterless than where people are driving, etc.

That's the issue, Sdcs don't have a fear or surprise in addition not intuition either.

It can't for example anticipate a person crossing the street from behind a vehicle and possibly prepare to brake if that person actually ends up crossing or if they are just getting into their car. A human driver would have their foot over the brake or be prepared to move away from them should they unexpectedly cross.

I'm not sure where you're from but people drive and follow the rules of the road when it snows in Canada. The only exception would be the lane markings being covered but my car can't see the lane markings when it rains anyway so that's not a snow issue.

Also sdcs can misread signs, a human far less likely to do so. For example HOV signs.

You fundamentally don't understand the tech you're talking about.

Fear and surprise doesn't make faster reactions, it makes worse ones. Imagine sdcs are people driving where time is slowed down 100 fold. Their reaction speed is that much better. Reaction speed to a sudden object for a person is 750ms ... a sdc is maybe 20ms. It isn't close.

And yes, when snow covers lane markings, humans stop using them. They also drive to avoid deep snow and ploughed snow. This is very erratic behavior that needs to be learned. Vision isn't the issue. With some radar types and quality maps, a sdc could see like it was a clear summer day during whiteout conditions.... but other drivers would appear to have gone insane.

I don’t have to understand the tech. I’m testing it every day with real life scenarios. It’s not anywhere near ready.

You are so sold on your beliefs you’re not looking at reality. Have you not noticed all the car ads stop pushing self driving and more towards driver assistance this year?

There’s a reason.

P.S, You can downvote me all you want but that does not change the facts.
