Well....i'm going against the grain then.
Before we start...if the wind was really bad and threatened to put you into the kerb, and thats the reason for riding in primary 90% of the time...fair enough..no comment to make really.
But otherwise..
Your riding seems very defensive or assertive(depends on your definition of primary) JRG..half the time, youre very nearly halfway in the road. You have a much wider cycelane than our local council have given us, yet you dont use it at all.
I saw VERY few drains or potholes in said lane, and it was probably drier in said lane.
Yes, its your right to use the road like everyone else...no doubt. But as a driver and cyclist, i'd be very slightly confused why you're halfway in the road. That said, personally, i'd pass you better than the other drivers did.
The opening shot with WVM, after hes gone, you maintain primary as you approach the very next left jctn...why? I dont see anything approaching from the left.
As you leave the R/A and move toward the traffic lights, you have primary nearly all the way...but why. Theres nothing approaching from the left, and as you near the lights, theres seems to be plenty of room for all if you moved into the cyclelane.
I ask why...there may be good reason, i just cant see what it is.
