I look before doing any kind of turn/lane change/pothole avoidance, but on a continuous road there would be more risk from imbalancing myself by looking over my shoulder all the time than just looking forward and hearing what's behind me. I figure it makes overtaking me easier if I'm concentrating on cycling a dead straight line than wobbling around trying to see what's coming - because it's coming whether I like it or not.
The ones where shoulder checks are really important are where the distance between me and a right turn, and me and the approaching car from behind, would result in the car overtaking me just as I wanted to turn right (the distance is 'just short of a length', if you ever played cricket). So I end up slowing a little, playing it with a straight bat and hoping I don't get bowled a yorker from the New Road end.
