The hon. Gentleman’s Bill is a good idea, because we all have to work together on air quality to lengthen the lives of many of our constituents and certainly of many people in the hotspots. That is where electric vehicles, the charging points, taxis, buses and all those things come in. We need to look at hydrogen cars; we need to look at a whole range of vehicles, and perhaps sometimes we need to take people out of vehicles altogether. Norman Tebbit’s “On your bike” may have a whole new meaning. If people go to work on a bike, that is good for the environment as well as for getting to work.
