When you are playing with another person. At Martinsville when a caution comes out and all the cars in front of you get bunched up, when asked to pit, put yes and when you pit(if the other cars do not) hit abort and it will take you through the pits at the same speed as the cars are going on the track, but you do not have to go as far. You will come out two or three spots better then when you went in. You can even get in front of the pace car. But all the cars have to be bunched up. If one car goes in befor you, it will let the rest of the cars catch up with the pace car. (in turn, they go faster to catch up with the pace car)
