EBD, F Duct, Double Decker diffusers, to an extent the flexi-wings. There's been a lot of innovations by engineers and designers of different teams, particularly since 2009 and on the whole they have been legal (the flexi-wings less so) but every time a new innovation is come out and proves to be beneficial to the team it gets protested. However, we seem to be getting into a vicious circle
Not only is it time wasting, it's costly, teams will have wasted millions on all these various designs, and for teams like the ones at the back (and maybe Sauber who aren't the richest team and aren't overburdened with sponsors) it's too costly. It's also taking money away from general development of the car. Bernie Ecclestone is very keen to stress about how F1 needs to cut its costs, but if this situation was managed better, there would be a large saving anyway.
It also seems like F1 is being ever so slightly nudged towards a spec series, whenever a new innovation appears on a car and it helps the performance, the other teams immediately claim that it's illegal and we go on that circle again. Engineers and designers are clever people, they will find loopholes in even the tightest regulations (just look at Newey) but that doesn't necessarily mean it's illegal and that they are cheating. Personally I think it's more a clever adaptation of the rules and fair play if they've been able to legally make an advantage to their own car even if the other teams can't easily replicate it and if they can't, tough, that's what development is for and they'd save a lot of money and it wouldn't exactly be wasted money if they tried to replicate the system as it wouldn't get banned a few months later from the FIA.
- Team 'x' comes up with certain part that is unique to that car which is legal and provides speed
- Other teams protest to the FIA and Charlie Whiting
- Initially the part in question is passed legal and the other teams spend millions of pounds developing their own version of the system
- By the end of the year the FIA decide to ban it altogether and the teams have wasted a lot of money (and also may have to change their designs for next years car as the device may have been a part of it)
- Repeat the season after with a different device
