Black cab drivers see red over needing less Knowledge

London's black cabbies, not renowned for their rosy outlook on life, have been given something to complain about – their exams are being made easier.

Passengers all over the capital are being treated to self-opinionated rants on the introduction of a new "Blue Book" – the bible which taxi drivers have to study for up to three years before they can say they have "the Knowledge".

Transport for London, which issues licences through the Public Carriage Office, has slashed the number of routes prospective drivers have to memorise from 400 to 320. At first sight, simpler routes to becoming licensed might appear to be something drivers would be in favour of.

But yesterday, the cabbies were warning the changes would spell the beginning of the end for the world's most knowledgeable and honest taxi drivers by allowing new, lower-calibre members into their elite club. "At the moment, the number of runs to be learned requires dedication, skill and a pride in the job that we think will disappear if the Knowledge is made easier," said Richard Massett, a spokesman for the Licensed Taxi Drivers' Association. "It will also result in an increase in the number of licences issued and that will make it more difficult for our members to make a living."

Ken Livingstone, the Mayor of London, has made it clear he would like more taxis servicing the capital. He recently tried to attract more drivers on to the streets at night by agreeing to increases in night-time fares.

Transport for London said the new book had reduced duplication of routes and was not part of plans to increase the number of cabs.

In the finest traditions of the London cabbie, however, the drivers' association was not satisfied. "If I were Mr Livingstone, I shouldn't get into the back of a cab for a while," said Mr Massett. "If he did, he'd more than likely get a good talking to by the driver."
