Taxis comprise an important element of the transport universe. They cover the first or final miles of many trips. On-demand personal transport in a three-wheeled rickshaw or tuk-tuk is one of the joys of travel in Asia. Sometimes, though, you need a taxi for a long-distance journey.
To reach a flight from Tbilisi to Luton last week, the only way to get from the Armenian-Georgian border to the airport was by taxi. The driver, who also chaperoned me through the frontier formalities, wanted only €60 (£52) for the 90-minute journey in a vehicle almost as old as he was.
