Driver prioritisation over system
If the driver takes clear evasive action or brakes during the collision
warning or braking intervention phases of presensecityactions,
the current actions of Audipresensecity (e.g.early warning) will
be suppressed or cancelled. If the obstacle is no longer relevant
after this, Audipresensecity will cancel assistance in this case.
