Is launch control any useful?

Hello,

I know that if you press the brakes and then accelerate, when you release them it launches the car.
Pretty cool except…when is it useful?

All the races start without a countdown (seriously, that’s the most ridicolous way to start games, even smartphone games have a 3…2…1… but not this one :'D) so you can’t setup a launch for that…so what, is it just for swag, like 99% of content here? :confused:
