[Germain Donne]

Or maybe a ringing bell of some sort that starts giving out a sound when there is about 5 minutes till the race begins.

Or even both, a bell that makes a sound and a notification on your screen, its doesnt have to blink red and be an alarm totally ruining a hotlap shocking someone to death, but just a small.. kind of, Hey, your race is about to begin, nows the time to get your drinks and snacks and make ready.

That way you could... watch some television while waiting, which would be quite nice.

A notification, without the option to sound, kinda takes that away...
