Change game speed in Single Player-mode
At the moment you can change game speed only when you're watching replays. The slowest possible speed is 0.125x and fastest possible speed is 32x.

As a person, who runs offline leagues and loves to organize endurance races where only AI-drivers are allowed to drive (even in multiplayer, believe it or not!), I would love to have an ability to change game speed when player is watching a race in Single Player-mode. Preferably in the same way that you can do at the moment in Replay-mode (use F2 to decrease game speed and F3 to increase game speed).

Just for security/safety purposes, perhaps it could only be possible to change game speed in single player when the player itself is not driving.

It may not be really useful, but watching up to 48 hours long AI-races on normal speed can really waste a lot of time especially when you want to test numerous amount of different setups for AI-drivers to ensure that they are as fast as possible when they're going to drive (endurance) races in single/multiplayer.
I see a problem with this due realtime physics calculations - doubling the speed would mean doubling physics calculation rate,also AI virtual "brains" would load the CPU twice as normally. Making it 8x faster would load quite heavy most CPUs normal PC users have. In replay there isn't such problem due prerecorded car positioning.
