Sadly London is unique
And historically speaking, held to ransom by black cabs. I've lived here for nearly 40 years and I've learned to avoid using black cabs whenever possible. Yes, there are a lot of nice cab drivers out there, but I cannot stand the back-breaking discomfort of those older cabs, plus getting thrown around, not being able to see through the misted up windows...
That's even before we talk about the cost. For me the killer blow was the rise in fares after 20.00, Boris's Big Idea to get more cabs out and about in the evening. Can someone explain the logic?
Quite honestly I've never had a problem with a mini cab driver, with or without satnav. Strange I note some down votes on Addison Lee, personally never once had a problem. Clean, recent model cars or MPV's, clean well-dressed and pleasant drivers. GLH is another excellent London-wide company.
As several others here have said, the cabbies have seriously shot themselves in both feet by this action, but the real problem is that it's London's problem and the law needs to be changed. There's plenty of room for all these cabs and the black cabs would still have the advantage of kerbside hailing.
I signed up to Zipcar (car club) about 2 years ago. Totally brilliant, I've rented several. On one occasion I rented a car to pick someone up from Kings Cross to bring back to Chelsea. 1.5 hours - it cost me £9.00. No contest as far as I'm concerned!! Another time delivering 3 computers round west london, took 3 hours - £18.00. No congestion charge, fuel included.
