London cabbies: Brain cell mightier than microchip
Satellite navigation systems may be the latest "must have" car gadgets but London cabbies, who have to pass the world's toughest taxi exam, are not impressed.
While hundreds of thousands of the electronic mapping devices are sold every year -- despite some reports of software glitches that have sent drivers down one-way streets or up impassable mountain tracks -- most cabbies in London regard them as largely irrelevant.
The increasingly sophisticated devices were allowed in London cabs for the first time earlier this year, but so far few drivers have opted for the hi-tech guidance systems, preferring instead to rely on their own brain power.
