We need to go up in a helicopter to take a holistic and comprehensive view of our public transport network. We need to look at the hierarchy and put walkers at the top and then have cyclists, riders and drivers. However, we must also recognise that, if we have a really good public transport system, it requires our buses, our trains and our taxi drivers, as I recognise that they too are an important part of it. The challenge, I suppose, is how we use the road space that we have to recognise that it is an integrated transport system, while being mindful of environmental improvements and benefits. It is an issue that I am aware of. I am very much focused on COVID-19 at present, but I know that it is an issue. I had started to engage on it just before the crisis hit, and it is certainly an issue that I will engage on further.
