Now, now. Dont be harsh. They dont deserve being burned to the ground.
Look at it this way. Everytime they put restrictions on the F1 engines, it makes the teams dig deeper into their research and testing to develop better engines. This research in turn, gives us more powerful, reliable, and efficient road car engines.
Truthfully, if it wasnt for F1 and the advances it is has made over the years, we may....just may not have been graced by the production of the glorious V10 in the M5/M6.
Heck if it wasnt for Rally restrictions on engines, would you think the Evo and STI road cars would be so good?
