Our view is to support their concerns, and I should say to you, sir, that they are members of the RAC. I know they are appearing later this week on their own behalf, but I'll let my colleague speak to whether or not it is a real issue for us. It is an issue for the commuters, we believe. I'm not sure it's at the same level of concern with other operators.
Perhaps, Paul, you may want to speak to that.
