Sick of standing in the rain desperately trying to flag down a cab? Well UK black cab firm Zingo thinks it has the answer to your prayers — its taxi-hailing service.

By calling a local-rate number — 08700 700 700 — the user is automatically connected to the nearest taxi operator which finds the closest driver, who can then automatically find the passenger and give them a collection time.

Zingo uses GPS (Global Positioning System) and location-based technology to locate both the taxi driver and the passenger.

The service costs £1.40, on top of the standard cab fare and will be available throughout London from April, with expansion throughout other cities in the pipeline.
