The online racing simulator
Free practice, quali change and warmup
Instead of starting qualifying with the cars being parked up single file before the final sector (and shift Sing teleporting to the start grid), It would be much better if they all started in the pit lane in garages.

That would make it more realistic and probably have less ability for crashes in qualifying - which suck.

Also, free practice and warmup sessions (good idea Tristan) are needed for leagues that want a practice session between qualifying and the race. Setting warmup length to PF should be "no practice session - keep fuel, tyre wear but not heat, damage and setup".

I dunno about the practice and warmup modes, I guess it could be of use, but you can do that after a session ends... only it just doesn't show your lap count or laptimes. It's still enough to get some practice in, but yeah... if or when the session ends, if there was some better sequence of events to simulate all the sessions like in reallife, that'd be nice for a league.... but not so much for the random public racing.
