Just another illustration of a type of close overtake and (nearly)-left-hook situation: just this afternoon (on a rural 'A' road) was overtaken far too close by a white van which then cut in very close to the verge, forcing me to brake. But the difference here: he was not turning left (indeed there was no left turning) nor avoiding an oncoming vehicle, none of the usual reasons: no: what he was doing was giving himself space to turn right into a narrow private entrance. The turning was awkward and he needed to move well over to the left to negotiate it.
As with all the other cases, he could have waited: he'd have lost all of a second I reckon. Not an incident worth more than the usual invective, but still makes one think...
