Is under braking....when they go right, first leg. They miss the apex and choose go straight....cuting the chicane. Eventually some hit the wall, eventually some continue, to the next lap, going straight again.
When they are returning to pits after te qualifying lap, they miss the chicane, an stay there trying to find the correct way, the other cars also come, go straight, and they go colide. A lot of cars with broken wings, broken noses, loosing wheels....and stuff.
To be more precise...they don´t go straight without lift off...they brake, but it seems that it´s not enough...and they cut the chicane.
