That's simply down to price/service Ken

Addison Lee offer a reliable service at a transparent cost, hence alot of corporate customers choose them as a company ( regardless of individual drivers).
What I was trying to suggest Geoff was simply if it bothers you that much then perhaps you should either become a licencing officer or find a job with the traffic polis

As I said earlier, before jumping to conclusions, consider why that person has done what they have. I'm not defending the behaviour of others. Certainly a vast number of people who could behave better on the roads should know better, but don't tar everyone with the same brush.
Perhaps we should all be retested every 5 years or at least have a probationary aspect to the licence which limits new drivers to the number of passengers and curfews. Follow this up with a written test and a two hour extended test.
As for the two jobs thing, having worked 60+ hours a week practically since I left school, I agree that people have a right to work. I only referred to it as the only stereotype I know about fireman is that they are all plumbers. To put that another way, I know two firemen and they're both plumbers. Most of the taxi drivers I know are decent people trying to earn a living. Thank you also for answering my earlier question.
