as i'm riding so if i see cars on the outer right lane moving
very slowly i will change to lane 2 and check for safety before
over-taking..
I sometimes do this. At exits of expressways.
Exits to expressways usually have a dedicated turn-left lane
marked by dotted lines. The lane to the right of this, is the split
lane, ie. straight-and-left arrow lane.
Sometimes when I am in a convoy at the
dedicated turning lane, a hotshot would zoom in and squeeze
into the stopping distance space infront of me. This would cause
him to tailgate the vehicle infront and I tailgatting him. If the
right lane is clear I would then change lane and drive/ride
along side the hotshot, and exit the expressway. That driver
usually a late 20-30 male would look straight,
not wanting to look in my direction. I think he realise
that he need not cut into my path, and that he could easily
make the exit from the split lane. Ha! some expert.
