it is a generic and a transport vehicle one too !, but unlike bike or auto it is a rather unregulated and runs more like a personal small business,
cars or scooters would be great to monetize as online search or for hire would be good,
hard to envisage an online portal hawking cheap rickshaw fares ( autorickshaws too would not pass this test , getting fitted with gps to regulate fares makes it even more daunting !
however a manufacturer may be interested and then this domain might see an enduser at the end of the tunnel ,
then halelujah et all...
untill then , ruminate on a transport niche domain with non-uber potential
