You're approaching this the wrong way. What do companies like Porsche and Nissan want? Profit. To do that you have to sell, and you better damn well market your cars like they've been test driven by Jesus. These Nurburgring records are not for imaginary bragging rights, they're for marketing. As long as doing this will get them more attention they will continue using the Nurburgring as their standard. Nissan, Porsche, Chevrolet, and Chrysler are not the one to blame for this Nurburgring rivalry and they are not ridiculous or stupid. Nissan is genius for having used the Nurburgring to their own advantage. The one who is being ridiculous is the general public that just doesn't know any better. Frankly, they will never know because explaining such a thing is just so time consuming and pedantic that they'll have gone off and started Youtubing another lap time before you can finish.
