Maybe in qualifying, an idea could be how fast (or slow) you are through each section. For example, i set a time one lap, then the next lap i am 1 tenth faster, it could display that on the screen.
Im pretty sure that everyone has come across the noobs as mentioned above. It is especially annoying when it is a packed server, and that they do not know the track. Maybe there is someone of stopping newbies joining 'filled' rooms straight away. Maybe offline they have to do a certain number of laps. Im only posting this because ive noticed it a lot recently, especially with them blocking the track at the Oval etc.
