In his report from Antarctica on Radio 4’s From our Own Correspondent, Justin Rowlatt shed tears at the collapsing ice-sheet. Yet still he found a reason to hope. He concluded that humanity’s defining characteristic is not belligerence but cooperation. Precisely. Our instinct for cooperation is the wellspring of my critique of the traffic system and blueprint for reform. In 2012, Rowlatt co-presented a BBC series, The War on Britain’s Roads, in which such critical insight was absent. It’s good that he is showing signs of development. This was my critique of the 2012 series.
