That makes no sense.In response to the OT, GT has grid starts to try make things a little less chaotic going into the first corner.
Its why beginner and intermediate races have rolling starts, but expert races have grid starts. I guess it's to ease new players into the series gently.
Grid starts are easier than rolling starts. Its far more easier to overtake and get in a decent position, instead of being stuck at 16th place and 15 seconds behind the leader. So why would they be absent in beginner races but present in expert?
