After hearing the ripple of applause at the end of the race I realised that LFS is skimping on some decent and realistic background sounds to create more of a sense of 'being there'. The applause is more akin to a tennis match than a race track.
Probably most importantly, you should be able to hear the trackside commentary echoing round the place, (an incomprehensible murmur will do, just like it is in real life ). GPL did this when you were sat in the pits and it worked really well.
There are other noises that make up that racing atmosphere, such as engines being started up when you're in the pitlane, the air horns when a group of fans spot their driver, or the ridiculously loud warble to warn that a car has entered the pitlane.
