Minister, it's Love Your Lungs Week, and I know you will wish to—[Interruption.] Here it is. I know we all wish to commend the British Lung Foundation's work. Indeed, we had our photograph taken outside the Senedd earlier when we were chatting about the need for a clean air Act. But can I tell you that it's also official that the quickest way to travel in Cardiff during the rush hour is by bike? A group of Cardiff councillors, volunteers and other campaigners raced by the various modes of transport to Cardiff castle. Actually, 'race' is perhaps an exaggeration for some of those modes. The bikes averaged nearly 12 mph, buses just over 6 mph, and bottom of all, cars—barely 5 mph. It's quite clear that active travel is one of the greatest ways to promote not only efficiency in terms of commuter travel but also clean air, and I commend all those activities that promote these modes of transport.
