So, 5mph on roads that already have tracks for the car to follow and barriers for it to see on either side. Curbs that aren't buried. Street signs and lights lining the road.

I live 5 miles outside of the nearest town and frequently have to drive long before a plow hits the road and long before it has warmed up enough for blacktop to be visible. That video doesn't even prove they can handle ACTUAL conditions when it's snowing in anything but the most ideal situation and at a speed that would require me spending 4 hours to get to work.

I mean... it's better than nothing but it's definitely not something that changes my mind on it being ridiculous to think that's replacing a human driver anytime soon.

It heartens me to see this. Still very early in the process though - that's pretty close to the best case snow (it is awfully wet, which can be a pain), perfectly clean sensors, great visibility, and moving at about 5mph (as a point of comparison Montana drivers would be going at or near the speed limit in similar conditions - >45 for the gentle curves, 25 leading into the right angle turns).

I also saw the car starting to break free (i.e. start a sideways slide) just as they clipped to another scene; that's what I want to see more of. It's an unavoidable occurrence in winter driving conditions, and the proper recovery to those is the most important skill to learn to drive on snow.
