Primary position, for me, is where l am in the carriageway and that deprnds on a number of factors - time of day, what day it is, traffic flow, obstructions e.g. tree roots, manholes pot holes and other things
Secondary position is sitting outside a coffee shop with a cappuchino!
What amazes me is that some cyclists do not know their route; yes, l know you can tell me how to get from your home to your place of work or from home to the outskirts but how many are aware of the constants and variables? That pinch point at the bottom of the High Street was there yesterday, is there today and will be there tomorrow so that should not be a surprise to you. Those traffic lights that you passed today will not decide to go walkabout all by themselves or will they? If your local team is playing at home, you know traffic will be heavy there and there will be strangers who do not know the way. The market is only open a few days a week so you know there will be heavy traffic on those days, same with schools.
How long does it take to learn a route and the best line to take? For some of us - only a few times cycling it but for others - never! I moved here from Bangkok about 3 months ago, most of my cycling has been heading south west but decided to venture east yesterday and explore. So what did I learn yesterday? The most important things were terrain - mainly flatish, traffic flow - starts to diminish after Hwy 205 crosses Hwy 2 at Cho Ho. The frontage road disappears as you get to the town and reappears on the outskirts (Frontage road - road that runs parallel to main highway but is separated from it by barriers but has various access points every few kilometres).
Too many cyclists are blaming the other road users for their poor cycling. If you see a car close to a pinch point, why don't you just ease up and let him pass or is your attitude "They shall not pass!" Is it worth getting all worked up and letting your blood pressure rise, just to save micro-seconds on your commute? I am not saying be meek and mild, by the way.
Confronting drivers - you catch more flies with sugar than with vinegar! I'll give you two examples; the first, i was a passenger in a Bangkok taxi which was involved in a near miss at traffic lights, the driver grabbed an iron bar from under his seat and attacked the other driver. When you confronr the other driver, is he armed? You do not know. The other incident was a few days ago, cycling back and I was passed by an old Iziussu pickup, fairly low speed and the wing mirror brushed against my leg. He stopped a few hundred metres up the road, I stopped by his car, big grin on my face and with a mixture of Thai, English and signs, said "You were a bit too close, cocker, leave me a bit more romm in future." He smiled and apologised Close - yes, worthy of a youtube moment - NO!
So, please, enjoy your cycling and don't sweat the small stuff.
