Not sure about the weaving bit - looks a bit like a wannabe trying to warm his tyres up!
What I try and do is move across the carriageway from the side of my lane that I'm on, onto the other. And back again as required to which ever position in the road put's the most distance between me and the vehicle at the junction.
The movement of your machine (headlight) from side to side is what makes you and the machine stand out from the background.
Doesn't always work though
. Ask the Czechoslovakia man working for Manchester company, driving a company car on his way to work at Inverness airport why, after looking directly at me as I came round a roundabout, he pulled out into the side of my bike as I passed infront of him
Just my mutterings
