Cyclists are often called out for not stopping at stop signs but that complaint is usually reserved for those who blast right on through with little or no attempt to slow down. What I saw in this video were reasonable efforts to follow the law - not perfect - but good enough for me and good enough for most people. If a cyclist had done exactly what these cagers did, very few would have any complaints.
I've stopped at similar intersections - on my bike - signalling a right turn - and been passed by another cyclist on my right zipping between me and the curb at about 15 mph. That's the kind of thing that gets motorists mad at cyclists.
