Finally, halfway thru the video, "Let's see if we can help people"!!
Here's another idea. Drive a mile up the highway, and see if you can start flagging people down, to at least give them the idea that they need to slow down, BEFORE they reach the multi-vehicle pile up??
Or, you know, maybe dial 9-1-1 on that phone? (might have already done, but still....)
You realise that is probably how the pile-up occurred, don't you?
Long straight road, poor visibility. Cars are probably driving at a distance so that they can see the car in front, but they're keeping their distance. However, the speed is still too high, so when something happens to the vehicle in front, they all plow into each other.
It really is as simple as that. Assuming that the person at the front is driving at a sensible speed is stupid because there's no basis for the assumption.
Yeah, dealt with that sort of thing when I lived in California's central valley, and had to drive through the pea soup "Tooley" fog there. You just sort of drive along, completely blind, hoping and praying that the person in front of you hasn't stopped or crashed.
It was that, or just don't drive when it's foggy......which can easily be 1/3 of the year! What's really crazy, is when you get the fog that's only ~6' thick, so the cars are completely blind, but the trucks and buses can see forever in front of them.....just not the road in front of them!
