According to a 2003 study, rubbernecking was the cause of 16 percent of distraction-related traffic accidents. That's a lot, when you consider the fact it's 100% preventable. In the Netherlands and the United Kingdom, incident screens have been designed that can be erected around vehicle accidents to discourage rubbernecking.
Isn't it great when you're creeping along the highway on a Friday afternoon in the 35 degree heat at the blistering pace of 20KPH and thinking "Be patient, there must be an accident ahead" then you get close enough to see that, sure enough, there is indeed an accident... ON THE OTHER SIDE OF THE HIWAY! Then you want to lose it! But I feel so sorry for all the rubberneckers when you see that there's no guts and brains splattered all over the road. They must be so disappointed.
