After bargaining the price, the driver will take the passanger to one destination.
The taxi bike was often used by the inhabitants of cities for example in Jakarta, because of the surplus from the other modes of public transportation, and also is much faster. Moreover Ojek could cover areas with crowded alleys which was difficult if driving by car.
Usually they're waiting for passangers on the busy intersections, or on the road that leads to a settlement complex.
