It is quite clever. My own rule of thumb is "add half of the amount in miles, then 10% of the (original) amount in miles". What's interesting is that it happens to be just as precise as the method shown above (ie. 1.6 v 1.609 v 1.618 )

But ITV News has uncovered an operation that penalises people who do just that to travel to London Stansted Airport.
Despite having contactless payment systems activated on the gates of the Stansted Express, thousands who don't have a physical ticket are being given large fines of up to a hundred pounds.
