Seriously? This is professional automobile racing, not the defense of the republic or a religious holy war. These people are engaged in an activity that rewards their best competitive efforts. Up to and including finding the limit of regulations. Surely you're aware of the history of things being pushed beyond regulations. By calling it cheating you've chosen to apply a moral judgement. And that's where the whole thing comes a cropper. Participation in racing, unlike society as a whole, is strictly voluntary. A bit like society there are both written and unwritten rules of conduct. In the case of racing, those rules permit a much edgier, more aggressive approach than society. At no time does anything anyone has done in this sport deprive those not directly involved (by their own choice) in life, liberty or the pursuit of happiness.
