Re: Follows old adage...
"it would allow the rich teams to build a different car optimised for each circuit"
It would also allow somebody with a really good idea to come in and trounce everybody. A really good idea like moving the engine from the front to the middle of the car which revolutionised the entire sport.
"or (cough 1980s Renault) a car which would only last one race."
Did they always last a whole race? McLaren would have been envious of an engine that did that last year.
