Dependent on the time of day and your location, hailing a London cab is often a random game of chance - will you, or wont you, manage to find one of those welcoming golden lights which stays lit all the way along the road until it reaches you? A game of chance, of course.Prefacing this with a "I have not used this service yet", it was a very pleasant surprise to hear of a fab use of technology in the London cab market. TweetALondonCab - yes, send a direct message on Twitter saying where you want to go from and to, and a cab turns up. Start by checking their Twitter page and their website to see how it works. Good luck, guys, you are ahead of the game.
