Black ice causes pileup - GIF

[Frank S]

In reference to the original video, WHY is it that when people are running for their lives,
they never take the shortest path to safety. Instead they try to outrun the danger,
instead of just stepping aside and letting it go by!! Why not just step to the side of the road?

Because people's minds shut down in a panic situation, their only instinct is to flee there is nothing left to tell them to seek the bast pathway to safety.
