Rallying never really needed manufacturers, they are only needed because of the stupid homologation fia-cashcow rules.

Everyone should be able to build and drive a car as long as its build according to the rules, just like in wrx or f1 or dakar or lemans or..

The forced need for manufacturers aproval has been holding the sport back for many years now. Without that rule, we could have seen many private firms operating their own cars, just like ik most other motorsports.
