Addison Lee drivers told to defy bus lane law (and to just say SMIDSY)

The knowledge is a pointless rite of passage.

It doesn't make black cabs better, it doesn't make the drivers better, it doesn't make journeys faster or more comfortable.

It does add a layer of money-making bureaucracy, and allows the PCO to maintain their anti-competitive monopoly and monopsony, and it also gives cabbies a massive fucking sense of entitlement and self-righteousness.

But it does mean they can drive through central London without their eyes fixed on sat navs. Which in my opinion represent a far greater danger to cyclists than drivers on phones.
I cannot understand why sat-navs are not banned in Central London. If you don't know where you are going, you should not be a cab driver, or even really in a car
