There are always grey areas to exploit in any set of rules or regulations regardless of application, not just motosports..
Of course the 3 cheeters had a "wider & different perspective" since they did not participate in the process and are not aware of the "spirit" of the rules... They should be penalized for not participating not rewarded ...
In reality, though looking at those pics, that loophole is so obvious, it should not have been a loophole to begin with.. How did the regs not get specific about whether or not you are allowed to make your brake light and diffuser into one connected piece??
