About 1/4 of the way into the movie, the two kids are leaving the safe zone in London to go find their old house. After they sneak out of the safe zone, they find some motorcycles to ride to make their journey quicker. If you notice, the girl who is driving is driving in the right side of the road. The only problem is that they drive on the left side of the road in England! Although there are no police cars, and there's no one there to enforce the laws, I'm sure habit and instinct would kick in!
