UberPool now covers most of central London

Uber's ride-sharing service, UberPool, is now available in a larger patch of London. Whereas before it was limited to a small part of the capital, it now spans all of zone one and zone two, as well as Heathrow Airport. All told, the reach of UberPool has more than doubled across the city.

The service itself remains mostly the same, however. You simply open the app, choose the UberPool option and set your destination. Once you've specified the number of seats you need -- two is the maximum, otherwise you're not really sharing -- Uber will figure out the best driver based on their location and who else they'll be able to pick up along the way.
