Is it time to start calling out bad cyclists?

Dopey? I think it's pretty sensible to both keep 1 metre away from the kerb (car doors, peds stepping out etc.) and expect cars to not come within a metre of you when overtaking. I mean, that's actually pretty close if you think about it and I would feel pretty uncomfortable with anything less.

Agreed. My driving instructor is always banging on about "keep a meter's distance from anything at the side, leave moar room" so that's the official line on distance - it is designed to keep you away from, as you say, car doors and peds; two things that will hurt a cyclist a good deal more than it would hurt a car if there is contact (obvs the ped would come off worst in the car scenario but peds wandering out in front of us lot is a lot more common than them doing it in front of a motor vehicle). A cyclist maintaining a meter's distance is reasonably likely to also be a driver and would hopefully thus have more awareness of expected behaviour on the road, both from themselves and other road users.
