On most things to do with street design and road-user relationships, Ben Hamilton-Baillie and I are of one mind, but we diverge on one point. He says street design alone can achieve the desired behaviour change – from war to peace, intolerance to civility – however you like to phrase it. A clash the other day between me on foot and a driver illustrates my call for a change in the rules of the road to precede or at least accompany changes in street design. It was at the entrance to a supermarket car park. The driver was coming out; I was walking across the gap between the pavements. I was there marginally first, so didn’t break my stride. He drove on, forcing me to stop, so I slapped his side window with the palm of my hand. He stopped in the middle of the road, remonstrating with me for hitting his car. I stood my ground, saying he was an oaf for not giving way. Jaw jutting forward, he got out and came at me. I said, “Are you going to hit me?” Meanwhile, traffic had stopped, bystanders were gaping, a bus was making a big deal of passing the obstruction … He said, “No, but you shouldn’t hit my car,” and backed off. As I often say in such situations, I said he was in the wrong, but I blamed him less than I blame the rules of the road which promote intimidation and neglect of vulnerable road-users. DfT, Jesse Norman, et al, take note.
