The british government stopped handing out new rickshaw licenses a long time ago and expect the rickshaw trade to die off once the existing licence-holders retire or die.
The remaining rickshaw pullers are these really old guys who work around Star Ferry. Because of their age, they will only pull you around the block, if you are lucky. Seems like most just like to pose for photos.
If you had sex on the rickshaw, I am afraid you will be flying face-forward from the rickshaw once the puller drops dead from a heart attack watching you get sex.
