Olympic Torch Test Event - 1st Wave
This is the 1st wave of vehicles in the Olympic Torch Relay - with sponsors Coca-Cola, Lloyds TSB and Samsung having their own vehicles.
Presumably when the Relay is repeated for real they will be giving away soft drinks, money and electrical consumer goods?
Note that the lead car is from the Metropolitan Police - probably part of the Olympic Torch Protection Team.
