This is what I find annoying about drivers as a cyclist:
leaning out of your window to shout sexual comments or general “amusing” abuse.
thinking it’s funny to drive right up my arse and then honk your horn very loudly because it’s “funny” to watch me nearly fall off in shock.
trying to overtake on a blind bend or bridge, realising someone’s coming the other way and having to pass seriously close.
getting too close and catching me with a wing mirror.
overtaking me, then pulling up next to a parked car or to the curb and stopping, forcing me to stop when there would have been plenty of room for me to continue had you not parked your vehicle in my way. See also deliberately pulling up to the curb at junctions so I can’t get past.
not signalling at junctions. I have to guess which way you are turning- if I pull up to the right to turn right and you also turn right I have to cross your path. If I pull to your left and you’re turning left I cannot turn right safely. Indicate then I can place myself in the safest position.
oh and the latest- electric vehicle drivers who don’t realise I can’t hear you. Gives us both a fright when I look behind as I think the road is clear to manoeuvre and there’s a bloody car sitting on my rear wheel.
