It’s an evolution of sorts — from the rickety black and yellow taxis, to the comfortable radio fleet cabs. Now, TAB Cabs, the latest entrant in the radio fleet cabs market, promises to bring a higher level of comfort to the Mumbai commuter. “We are the first tendered radio taxi service in India with a licence from the Mumbai Metropolitan Region Transport Authority,” says Jagdish Purohit, managing director, SMS Taxi Cabs, the company behind TAB. “The others have simply bought permits from existing cab owners.”
