The hi-tech taxi firm Uber has claimed no-one should "bother" buying a car anymore, because it's easier just to call a cab. The controversial American company will launch a new service called UberPool in London at 4pm today, which will allow customers to save 25% on their fare by sharing their ride with strangers. But in a statement likely to anger the petrolheads of Britain, an Uber boss claimed its app was so good that it would discourage people from owning their own automobile.
