Let´s say international football associations banning a round footballs in the future. Saying round footballs are not environment friendly. They instead recommend cubic balls. What would happen?

When will electric rallycars be mandatory and only vehicles authorised by FIA? To me I think WRC will vansih. Only village rallies with old cars will be permitted by some exemption.

Maybe that´s the future.

I admit I´m just blablablaing...
