There are also additional sensors besides camera, lidar, etc.
Thermometer - is it cold enough for ice to form? Is the temp rising or falling? What's the wind speed. This can be from weather data feeds.
Road type - is there a bridge or elevated roadway? Those freeze faster. This can be from Maps I suppose.
Grippiness - This is something I do. On a straight wide street with nothing remotely near, hit the brakes. How fast do you stop? How much sliding do you get? Do you fishtail at all? Does not have to be fast - do it at 20 mph / 30 kph. With little "grippiness" extend every buffer you keep around your car appropriately.
Are self driving cars testing themselves for grippiness? They should be!
