Yep, the car sometimes brake too much to try to avoid the others or to kick them slowly, so yes it takes time to finish a lap.
@MarioRossi93i, I noticed in Formula E, the battery of the car reaches 0% like 100m before the end of the race with the auto drive (so imagine for a race of 20 laps, you fail to end the race ), I noticed this in New York track while in Berlin track it succeeds to reach the end of the race with almost 0% battery.
I don't how you manage to do the auto drive but maybe you can tweak it.
Thanks
