Revealing mistake: When Solo and Illya, posing as maintenance workers on the London street, are opening the manhole to go underground, two cars - a blue VW hatchback and a white roadster - pass them twice going in opposite directions each time. And while most of the cars are driving appropriately on the left, one pulls up behind them driving on the right (which is to say, wrong) side of the road.
