The plates have been blamed since the 80s. Yet drafting and the like was happening going all the way back. without plates, these cars with 100 extra HP would be in the stands and lots would die. It’s not the plates that are the problem. At least not solely.If you ask the drivers, it's the restriction plates that are the problem. Thats how they get all bunched up with no real throttle control of the power. Makes for some interesting racing for sure.
