The Scots clearly have no idea how much taxis cost in London. The Royal Bank of Scotland anyway. The bank has decided to roll out contactless card readers in London cabs. Good idea you may think.

Downtime is no expert – Computer Weekly’s expense sheet only offers the possibility of taking a bus – but is fairly sure £10 will probably only get you from one end of Oxford Street to the other.
