Anth, good timing, I was about to post a question to the forum.
As I am currently laid up, my wife is driving me anywhere of any distance.
So, yesterday morning we approach the lights at top of Marchmont Road, lights at red, we stop, indicating left to go along Beaufort Road.
Lights go green - and Alison doesn't move - odd I thought, until a cyclist passed our inside (at speed) and went straight on toward Kilgraston Road.
Apart from being incredulous at this guys move, I was so happy that Alison was aware of him, watching her mirrors etc as (had she moved off as normal) an accident would have been unavoidable.
Alison was (unsurprisingly) annoyed at the cyclist, but partly because she thought that she would be deemed at fault (maybe my influence re: bike/car accidents).
I said I thought not, as any vehicle (van/car/motorbike etc) should not undertake a vehicle indicating left at a junction - and shouldnt be any different for a bike.
However there are cycle lanes and ASL at the junction, so some cyclists perhaps assume this gives a right of way all the way across - ?
What would the police opinion be ?
p.s. get them to lock you up for 5 minutes, imagine that will be a cold sweat moment !!
