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.
