As part of a new incentive to cut down on carbon emissions and keep the city cleaner, transport for London have started a desi-style rickshaw service in various parts of the city, particularly at the west end and during weekends, as an alternative to black cabs and minicabs.
They're cycle-based (pedal powered) and carry 3+ passengers. I heard they're quite expensive but then again so is 'going green'.
These guys drive like crazy (majority of drivers are desi immigrants) and don't give a damn about others on the road...while driving through Edgware Road last Saturday night nearly ran two of these over!
