On 18 Doughty Street last night we showed a ten minute film about how Ken Livingstone is forcing London cabbies out of business. He is making every cab fit a piece of technology which is supposed to reduce exhaust emissions. Not a bad thing in theory, but the technology doesn't work. It doesn't reduce emissions, it actually increases them! Newer cabs have it fitted as standard but older cabs have to have it fitted retrospectively at a cost of £2500. The cabbies are issuing legal challenges but Livingstone won't talk to them and still maintains the technology works despite all the evidence to the contrary. He says it works if they travel at a constant 40 mph. With his experience of travelling in cabs, you'd have thought he would know that travelling at 40 mph isn't really possible in London, and even if it were, you'd get a ticket through a speed camera.
Anyway, watch the film and make up your own mind.
