Never done one here. Do you do a single warm up lap with the leading car judging the speed and distance between the cars, and then floor it out of the last corner? Or does GTL has something built in to control the rolling start?
Starting Procedure - Rolling Starts without a pace carRaces will be started from a stationary grid.
The polesitting driver will be responsible for leading the field around for a formation lap.
The polesitter shall wait until the starting lights turn green before moving off. They should not go immediately after the grid formation countdown finishes, or the simulation will give them a stop and go penalty.
The other drivers will move off only when the driver who qualified ahead of them moves off.
Formation laps shall be driven in single file. The leader shall maintain a moderate pace which allows all cars, including those in slower classes, to warm their tyres and brakes without struggling to stay in touch with the car in front.
The leader should aim for a target speed on the straights of around:
GTL: 50mph (80km/h)
No driver shall use excessive acceleration or braking during the formation lap.
Drivers are encouraged to weave left and right to warm their tyres, and to warm their brakes by dragging them whilst under power.
During the formation lap, each driver is responsible for keeping a safe distance from the driver in front.
Drivers should endeavour to avoid getting too far behind or to close to the driver in front.
Approximately 20 seconds before crossing the start line the leader shall slow to pit speed and engage their pit lane speed limiter.
Each following driver shall close up directly behind the driver in front and also engage their limiter.
20 seconds is the recommended minimum time that the leader shall have their limiter engaged before the start line. Where there is any doubt as to the correct place to begin the final start formation, a longer delay is preferred to a shorter one.
Drivers should not attempt to warm their tyres aggressively after engaging their limiter.
The leader shall not disengage their limiter until they cross the start line.
Each following driver should only disengage their limiter when the driver directly ahead does.
If a driver is unable to disengage their limiter, they should pull over so that the following drivers can begin the race.
A car reaching the start/finish line may disengage its limiter even if the car ahead has not.
Any driver who because of a technical failure stops, or who leaves the track (either by mistake or because of a failure), is responsible for rejoining the formation lap safely.
This may mean waiting until the entire field has passed and rejoining in last place.
The driver shall not attempt to regain their original starting position.
