I totally agree with you both about attracting other manufacturers. Look at the potential Audi/Red Bull link you, that would have been awesome but Audi would have looked at Hondas struggle, looked at Mercedes spending 3 years and billions on R&D to he where they are AND the testing restrictions, I bet they laughed Helmut and Christian all the way out of Germany.
F1 is so unattractive to car manufacturers and we have to rely on new teams coming in like Haas- great a new team, that's good, good for manor too, some one to beat....
They need to allow the teams who want to spend- spend and the ones who don't want to- don't.
We have no testing now and have a 2 tier championship, why don't we have testing which results in a better 2 tier championship?
