This idea sucks big time!
As seen the yellow roof black cab uses the oldest poorest cars, most poorly maintained, has no facilities, no call centers, no NETS credit cards payments, no lost ñ found services, no data terminals, no booking system, no printed receipts etc.
HK and other losy taxi service cities are like that, using 20 years old Toyota Crowns, in poor conditions, All because Privately Owned! No substential fleet size, poorly funded and poorly managed, un-organized to provide good standard of services, only lucrative to greedy individuals.
For SG fleet size of SMRT Transcab below 5000 are already too small! Comfort so STUPID can not Oust Uber and Grab, all fucked up. Cabby owned cabs will be 100X Worst!
They will be complerely fucked up! No Disipline Nor Rules, Dirty Smelly Rotten Old cars. Worst than Ah Neh India!
