Pillion-riding is associated with terrorist or criminal attacks in some South Asian countries. In Pakistan, for instance, pillion riding is often banned by local authorities around sensitive times, such as the Ashura commemoration, when there have been violent attacks on worshippers.
A motorcycle's dynamics will change when there is a passenger riding on the pillion. It is the driver's responsibility to compensate for this and keep both rider and pillion safe. The driver can and should brief the pillion passenger to avoid mounting or dismounting when the driver is unprepared, use the footpegs, let the driver lean into curves instead of trying to help, relax, anticipate braking and acceleration, avoiding a clash of helmets or a lean backwards respectively. The passenger should know signals to give to the driver, which the driver should recognise. Similarly the driver should consider the passenger, as well as the changed dynamics of the motorcycle, taking curves much slower, and leaving a longer braking distance, for instance.
