Re this argument for closing the pit lane during SC deployment. I see two problems...
ONE:There will always be a time after the race director has decided that a SC is required and the information getting out around the track and to all drivers. It is pretty damn quick, but at some tracks there's quite a gap between marshal posts (could be a second or so)... So when the SC actually is deployed and Charley pushes the SC button... A message goes out to all marshal posts, marshals then rush to grab the board and flags and hold them oout (that's going to take a bit of time), team pitwall crew are told, they then have to relay that info to the drivers.
The time between Charley deciding that the SC needs to be on track and each driver reacting could be anything from nearly instantaneous, to a couple of seconds. So when do you close the pitlane? What about cars that are lined up ready to pit (think of the loss of speed and positions coming off the Parabolica and aiming for the pit lane at Monza); cars actually in the pit lane (and what about that car that's only a couple of metres short of crossing the line when the light goes from green to red?)
It's workable, but the above example of a car that's decelerating to the pit entry line but is a few metres short when the light changes may well end up with a drive through later in the race, and could affect others' outcomes.
TWO:Cars pelting around a track on slicks... Suddenly rain! We know what happens, a car comes across it and spins out, crashes etc etc... Depending on the outcome a SC could well be called by Charley. Now the pit lane's closed and all the cars have to tippy toe round behind the SC with slicks because they're not allowed to enter the pitlane until the green flags are waved. How are you going to police that one? Especially if the rain was seen by one (or more) driver who (before the accident) dived into the pits and put on Inters or full wets? How are you going to disadvantage that crafty driver? How will you disadvantage the other not so crafty or plain unlucky drivers on slicks during the same rain, say in Malaysia?
Anyway... Just my couple of thoughts on this tricky subject... Just trying to point out that rule making/changing is a tricky business, it's a wonder the FIA don't get a lot more abuse when you think about it.
Too logical and reasonable? Tough!
