My commute-in normally takes me up this little hill (15/18mph) and back down the other side (22/25mph) - solid white lines for several hundred metres. It's quite a busy road in the mornings with a near continuous stream of traffic heading in to Cambridge. Everybody, motorists, buses, lorries, learners, police etc overtake straddling/crossing the white line (I wonder if a leaner would be failed if they did that during a test). It doesn't bother me, I don't feel unsafe. An odd thing is that the path on the right is shared-use cyclist/pedestrian footpath - this would normally attract the wrath of the get-on-the-cycle-path-brigade but its very rare that I get a beep or gesture from the traffic.
Out of interest, why do you not simply:
"take primary straight away as it is illegal to overtake, or remain in secondary and just glare at the people who pass me?"
Will certainly be interested to hear your thoughts on this. My guess and hope is that they are the same or similar to mine....
