Wrong on quite a few levels. When I first say the Nissan, I thought it looked awesome. The concept was fresh, and I was happy to have another large manufaturer in the big game. I never said anything negative about the Nissan LMP1 until they showed up at Le Mans with a car running at LMP2 pace. I dcouldn't care less about what excuses they have. You don't go to a race track as a large manufacturer, until your car is at least somewhat close to the other cars in the class you're competing in. Espicially not in the highest tier of motorsport.
It's about upholding a certain standard. And a massive company such as Nissan, with plenty of racing experience, has very little excuse to show up this unprepared. The excuse that they're using Le Mans as testing would hold water if not for the fact that both Toyota and Porsche, to mention the most recent inclusions in LMP1, both arrived prepared.
Not respecting the legitimazy of other opinions solely because they conflict with your own view on things. Now that is the essence of arrogance. Your tweet certainly embodies the spirit of a narrow minded train of thought. Stricking down any critisism as petty dislike of a company.
