Keep dreaming. This rumor has never been more than just wishfull thinking. The GT-series has allways been one of sony's most effective marketing tools for getting a good market share for the ps 1, 2 and 3. I can't imagine them giving this advantage up.
Well, as with any pickup server, The standard will differ from session to session. You will always have drivers incapable of interaction. Or children who go "WTF" or (in case of very religious people) "OMG" for every misfortune.
In my opinion the SR-fox server is better adminned but for some reason it does not attract the crowds like the FM-server does.
How about a server option to keep the tires (and maybe even damage) for the next race.
The option to pit for new ones (and repair) after finishing could remain but this would just give up the grid position that is gained by the result of the previous race.
It's such a waste to throw away a set of tires after just 5 laps.
IIRC KERS can only be deployed above a certain speed, 100km/h I believe. I think traction would be a bigger issue below that speed anyway (as you suggested).
I do not think kers will be a factor at this track. I can not imagine it will be enough to make a pass on this track and it's not necessary for defense here either.
