With brakes on, this close, and this weather, on an on-ramp, they are probs going 20 mph tops. Probably a lot lower since the cars in the other side appear to be at a standstill. Hence the picture being relatively crisp and clear.
I come from a land of ice and snow. This is routine for a backup.
Reluctantly crouched at the starting line
Engines pumping and thumping in time
The green light flashes, the flags go up
Churning and burning, they yearn for the cup...
You would probably drive more carefully with cake, than "the weather is bad", anyway. So probably a better way to advise. Cake and half full fish tanks, because you're too lazy to empty them the whole way...
