Reddle, that's the thing with writing on the interwebs and not talking face to face--the thing is I agree with what you say, as I said, I evaluate specific situations and do the same as you--but not all the time, and I have no problem pulling over for a few seconds to be courteous to some backed up cars at times too.

So ya, I suspect we have the same view, typing ain't always super clear and specific situations make me decide what to do anyway.

To emphasize again, I only have riding experience in northern Scotland, and drivers were really quite patient all in all.
But then I didn't ride on the A9 for example, not worth it to me, and I've done long trips in Mexico and Central America, riding into and out of big cities etc so I do have experience like you in all kinds of road situations and don't scare easily.
Cheers
