My hon. Friend is not only an advocate for walking and cycling but, in his high-vis jacket, a very visible advertisement for it. He is absolutely right, and that is another type of modal shift. Holland is in a slightly different position, in that it is a lot flatter than this country, which makes a huge difference. That should not take away from the fact that there are plenty of places in this country—London is one of them—that are pretty flat, and where there could be more cycling. Throughout our country, there is an opportunity for more walking and cycling. Those things have great benefits beyond decarbonisation, in terms of health, fitness and being outdoors.
