These cities in the UK that cost three pounds to cross half of. Are they some kind of special, tiny city? Perhaps made out of lego? An awful lot of taxis charge a couple of quid as the minimum fare just to get in it, so where you're getting these taxis I don't know.
Here's a big list. Even allowing for the inherent unreliability of the internet (and some of those prices look a bit suspicious), just which city is it that costs three pounds to cross in a taxi?
