I suppose maybe it's a city/countryside thing? Cars are great at long straights, but they take forever to safely clear an intersection compared to a bicycle -- and they block most of the road while they do.
It’s “normal” to be held up by traffic. It’s novel being delayed by a cyclist. Plus you’re doing something important and their leisure is getting my way!
When a cyclist does something unexpected, it’s extremely dangerous; pay no mind that they’re the one in 95% of the danger. When a fellow driver speeds, rolls through a stop sign, or fails to yield it’s lost in a sea of normalized deviance. No matter that car accidents are a leading cause of death.
And all their interactions with stupid drivers? Quickly forgotten a moment later.
The ones who take up far more of the road than necessary, granted because they can, and slow you down prior to traffic lights meaning you hit a red.
But when you hit a red, they swerve onto the pavement, across the junction with the pedestrians and then onwards beyond the red light while I’m still sat at the red. All while not dismounting from their bike.
In the UK, where I live they should stop at the light and not pretend to be a pedestrian. But they’re also entitled to the road, but when they ride in a manner that means I would have to veer well into the oncoming lane to get around them it’s just not worth it. A wee bit if there’s no traffic is fine, but not too much.
Isn't it also better for you that the cyclists get a head start, thus you're not stuck behind them in your scenario?
However, modern traffic lights tend to be designed exclusively for motorised traffic and here in the UK it's annoying because we don't have a "turn left on red" rule, so cyclists can end up waiting at a red light even though a left turn would be perfectly safe. I got caught out the other day at a set of lights that didn't detect me on my carbon bike, so I sat patiently waiting (the other roads were busy) until I figured out that my turn had been missed and had to carefully find a gap to make my turn.
The other thing is that stopping and starting on a bike takes significant energy and effort, so a straight road with many lights can turn an easy commute into a chore which is why it's common to see cyclists going through red lights. Interestingly, that kind of red-light jumping is allowed under some jurisdictions e.g. Paris.
