This is the trouble with letting manufacturers rule the roost in F1. They're not racers, and they're only in it as a marketing ploy.
In my opinion, F1 is much much better without manufacturers teams, who will up and leave as soon as their boards sense that further participation is not beneficial to their core business of selling motor cars.
And Niki's comment at the end about there 'being no more fans' [without the manufacturers]...? Yeah, right, Niki. Like there were no F1 fans in the 1970s, when the grid was full of garagistes and DFVs? Bring it back on is what I say!
