yeah, and you can edit your 'ignorance' crap out. Ive been watching F1 since before you were born, so just cos your a stupid little spaniard going against what everyone has said about the race, and the majority have said about the dull joke of a venue, doesnt make someone ignorant.
NEVER in the 19 years ive been watching F1, has the series been to such a pathetic venue. It wouldnt suprise me if we end up at some equally pathetic ones if theres money in it, but Valencia is a joke venue. Considering there are 2 F1 standard tracks in Spain, why the hell F1 went there ive no idea. If they had to go back to Spain, who 5 years ago you couldnt pay fickle folks like you to attend the races, then Jerez would have been a far better venue, and im sure theres a 3rd which is used over the winter (Jarama?), though it may be a Portuguese track (not Estoril).
As for the green light, as ive said... There are multiple buttons, my guess is the jack/trolly once the tyres are done, the fuel man, and a master button on the pit wall. I cant see as anyone else would need one, the trolly would put you onto amber once any work on the car was done (tyres, wing tweaks or repairs etc) and the fuel guys would take it to green i guess.
Also, when you consider that Bernie and co are constantly going on about all these places wanting to hold races, and they pick Valencia...
