Yea but we all know road relevance is bollocks at the end of the day.
Road relevance discussion always make me mad because there's only one real reason manufacturers GO racing, and that's to be faster than the other manufacturers because to the punters : faster = better.
You don't make a car to go racing and make it a #1 priority for it to be road relevant. The priority is to win and if it can be done using similar tech that you have on your road car then so be it.
If they really cared about road relevance, then in theory results wouldn't matter. All that would matter would be showcasing their road relevance.
Then you've got F1. Constantly trying to MAKE it road relevant. The only thing similar between an F1 car and a road car is that they have 4 wheels and even then the dimensions of the wheels and tyres are about as far apart as it will ever get.
