"The faste and most efficient way of bringing your bike to a halt, is simply ramming an immovable or proficiently heavy object; most houses, hardcore walls, large solidly rooted trees, and even parked cars, may all prove adequate. Alternatively simply steer your bike directly towards oncoming traffic, thus forcing a head-on collision, or simply plough through groups of pedestrians. When applying the latter method of braking, always consider that small children and elderly people with frail bones may not necessarily provide the required stopping power."
