Jim Park, at Truckinginfo.com, has a movie review of sorts—a look at five minutes of traffic cam footage showing a classic winter-weather pileup:
At one point, around the 3:30 mark, the scene starts to resemble a snooker table. Cars careening in all directions, only because they came onto the scene too fast and too close the car in front of them.
The video is instructive as it offers a glimpse of the dynamics of a multi-car pile-up. Most if not all of those crashes could have been avoided, I think, had the drivers modulated their speed for the conditions and left enough space between to take decisive and evasive action.
One commenter points out how quick people are to abandon their wrecked cars and take their chances on a slick freeway. Wild.
