"Who is going to tell him? I've been struggling to understand this. Is it aimed at me? If so, I'm well aware that this is a European study that covers 40 cities across Europe, but not London. So what does that mean?It's very embarrassing to have to explain, as if to children, the principles if research, but I'll have a go. Typically, research involves examining one set of circumstances and applying the results to a different but similar set: in this case, looking at traffic in European cities and, separately, outside the study itself, drawing parallels with the UK, including London.Now if it can be argued that traffic behaves differently on this side of the Channel, or indeed, fundamental physical principles like gravity, are different here than in Europe, your comment, Ed, is nonsense.
