This is
precisely why cycle paths and lanes are
less safe than riding on the road: a left turner on the right and a vehicle on the left going straight ahead, both of whom are adamant they have the right of way. Most accidents occur at junctions, not between junctions, so cycle paths reduce the minor problem, and increase the major one.
If motor lanes were laid out the same way cycle lanes, nobody would have any difficulty whatsoever in seeing the crass stupidity of it:
On the rare occasions I filter on the left, I generally stop as soon as the traffic starts moving, and always stop before the junction. Note that the cycle lane ends at the stop line about 3 car lengths
before the junction, which is probably supposed to be a hint to cyclists, but ends up being another obvious recipe for conflict. The guy in the video correctly concludes that both road users are to blame for playing chicken, but fails to spot that the highway planners are even more to blame for giving them the opportunity. If there's any room to argue about who has the right of way, the road design is plainly at fault.
Recently Jeremy Vine posted a video on Twitter of an impatient driver honking at him because he was in primary position following a junction, and he quite reasonably defended this by arguing that he was avoiding the door zone of the parked cars on the left. He then blocked me when I pointed out that he'd somewhat shot himself in the foot by cycling through the door zone to the left of the queue whilst riding up the cycle lane on the approach to the ASL at the junction.
