In theory, its supposed to work, but in real life, sometimes it don't, like when they throw in,
"you have to Finnish behind the man before you can claim his motor", if i could run with him i wouldn't need his motor. also the top 5 guys will make a deal with ea. other, if they Finnish behind ea. other they want claim their motors, so those 5 lap the field every week and if you don't Finnish in the same lap you cant claim the motor no way. they get faster every week.
