Driving south along the A12, at dusk today, I’m in the inside lane in a 70 limit with traffic outside me. A white van with – I think – “East Anglian Landscapes” on the side approaches the main road from a small slip road and edges forward. “He’s NOT going to pull out now, is he?” I think. He does pull out. Brake hard. OK, hard enough. Flash my lights, sound my horn.

A couple of minutes later, I pass him. I glance sideways, wondering who drives like that. Clean-shaven bony white guy of about 40, as it happens… on his mobile phone.
