In F1 car racing, the cars come very close to each other while taking a turn, and the gap between the leading and trailing car again widens after the turn is completed. There's a name for this effect. Anybody know the name?

In most racing circles it's referred to as the 'Accordian Effect'. You have to push your braking point back further when there's a group of cars to avoid rear-ending someone.

Answer 2

It's a real effect, called Drag Effect, which is used to approach the leading car, trying to do an overtaking position at the race. Normally, it's only really possible at the turns, where the car leading the race - or at better place - is followed for various laps by your rival, that car at moment of the race is faster than the leading car. At this instance, the car's pilot will try to overtake this place, at the race, and only get it standing so close to the leading car, tunneling his rival downforce to your car, and getting dragged. At approach a turn, the folowing car will have no problems to do an overtaking position, which normally happens at mid of the turn. The leading pilot has two choices at this moment: to lose the race place, or colide...
