Slow in, fast out
Typically new racers or novice racers that get to a new track are eager to get that super fast lap in from the start.
Just remember faster is not always giving you a faster lap.
Especially while cornering. Slow in, fast out is the trick. Start your first laps with a lower corner turn in speed. And try to go out faster instead.
Most of the time you overdue while entering the corner, wich will result in missing apex or going wide on the exit because of all the understeer you experience.
For example, start with the porsche. That car will teach you from the start that entering the corner will have to be slower then any other car.
