If they don't crack down on this McLaren, then they'll lose the old Ferrari International Assistance title.
Sarcasm aside, it would be nice if the rules allowed more experimentation, we might see some interesting new car deigns.
I loved the old days when the changes were extremely radical. A Tyrrell with 6 wheels, a Brabham with fans, a Lotus with sliding side-pods, another Lotus where the entire car was a huge ground-effect tunnel (didn't work, but radical), the mega-flat Brabham BT55 for instance, the CVT Williams.
