If you're coming towards the camera Primary is right in the middle of the lane, simples... but going in the direction of the shot pretty much every car coming that way goes over the marked centre line (there are always cars parked there). So where is the centre of of the lane? Is that the marked lane (well, no, I'd say, and that would be int he Door Zone anyway), or the effective lane as used? And, hang on... if that means the real lane as used by most traffic is off to the right of the line, does that affect the "centre of the lane" in the direction towards the camera?
Centre of the effective lane - I think Franklin is quite clear about this but I don't have time to type it out right now - and yes, it affects the direction towards the camera.
Indeed. The point I'm making is if Two Random Cyclists go and point to those spots on the road, they may not be the same spots. The Nice Thing about Primary is it's notionally a pretty sharp place, but it's actually a bit fuzzier in practice. (Also the case that it's not so much the Middle Of The (Effective) Lane, as the Mot(E)L +/- a bit of wiggle room. How much wiggle room? "it depends...")
