Although this taxi booking service was only launched 5 years ago - it is now worth $40 billion.

More than M&S.

Through your smartphone, you book the nearest available taxi/cab for your journey - at an agreed price and time.

Efficient, fast and new - in about 50 countries now; I've used the system in 6 European countries.

Sadly - the London Cab is becoming a victim. And having to accept the net, as a fact of life.
