can you imagine you carry one, Ah Lian brings one, Ah Huan carries one, Ah Huat brings one and I carry one... the bus will be very crowded, anyway if the whole scheme focus on convenience than why can't the bus company deploys more shuttle buses to all housing estates to pick up ppl (@20cents per trip) and send them to various bus stop and mrt stations, the problem is fixed right, of course if you have more objectives the solution is difference.
