Sports car racing is very popular again though, and Ferrari and Toyota have said they are keen to put their money back into it.
Red Bull have 2 teams that will leave if the cap goes through.
The FIA need to get a grip on this and fast. All they have succeeded in doing over the last few years is f*ck up the regulations and make it too complicated. They blame aero for no overtaking but the F1 cars of the 80's and 90's managed it quite easily and they had downforce.
The FIA have decades of F1 data at their fingertips, if they really wanted to they could come up with the solution, but as with all things these days they have too many people trying to make a bucket load of cash and screw the consequences.
I love motorsport but I F*CKING hate the FIA.
