really, instead of tightening those rules they should loosen the rules a bit, give teams freedom to develop things wich are useful for road cars too. The freedom for that isnt there now.
Isnt it ironic that with the more rules coming it became less exiting, since the 80ties the F1 became more dull and dull every year, with that there were added more rules year by year, so that is just the cause for all of this.
And the most worst part of those rules is that they dont even understand their own written rules, else they didnt have to rewrite parts everytime something genius happens(like LH's car not having enough fuel for the finish).
It is like the rulemakers think; 'Eh lets put these words together, it looks funny and no one understands it, so we can easily punish others for it, and when they did it we have something to do as it has to be rewritten.' the rules are simply stupid.
Just put up templates with dimensions and certain safety rules and let the teams themselves choose how to go there within the rules, it will allow really nice cars, and also differing cars
