Scores of Olympic athletes and officials have been making circuitous routes around London as untrained bus drivers transport them from Heathrow to the Olympic park in Stratford.
Two buses containing Americans and Australians got lost this morning even though their route was supposed to be fast-tracked by the implementation of the Olympic lane on the M4.
Two-time world 400 metres hurdles champion Kerron Clement told his Twitter follows he had got a less than favourable first impression of London, as the bus taking him to the Olympic Village struggled to find its destination.
The American was among hundreds of athletes from across the world arriving in the capital this morning ahead of the Games.
Speaking about the incident, London Mayor Boris Johnson quipped: "Clearly they would have had even more of an opportunity to see even more of the city than they might otherwise have done."
Australian official Damian Kelly agreed: "It would have been a great tourist trip if that is what you are here for". His bus, containing the Australian contingent of 30 officials and medical staff was taken past Buckingham Palace and the back streets of West Ham. It emerged after several hours that the driver didn't know how to operate the sat nav system on board.
