I totally agree with that - I just dont want to see no more invention being allowed because the rules have left so few opportunities to develop anything different
Its a very difficult balance the FIA have to strike. They have to keep the sport technically interesting as that is part of the core of what makes F1, but they also have to keep costs under control and racing interesting. With the recent loss of a number of big names you can understand why they have gone for quick/cheap approaches to things (like DRS) rather than more risky relaxing of the rules.
Personally, I think they are doing a fairly decent job given the big picture. Sure, some things are not so good (the whole tyres from Quali regulation still makes no sense to me) but things like KERS and the energy recovery systems coming in in 2014 are very interesting, and have the potential for lots of technical innovation.
