Help me please?

A while back I was watching some motor racing on tv and the commentator used a word to describe when 1 car follows another car into a crash. Many of us have done this at one time or another, and there is a word to describe this. Now I don't mean 2 cars crashing together, I mean 2 cars going around not too far apart, the car in front crashes and the car behind has the same crash.
I have used tractor beam in the past to describe this, but I would really like to find out what this word is. I did as many people last weekend at the National, but none knew, some of those people I asked think they are very clever as well Lol.

So over to you my fellow oOpler's, does anyone have the answer?

Cheers
