I’ve had this a few times, if you slow down to check the car i sgoing to give way it invites them to floor it and go through, keep approach speed up but cover the brakes, if they don’t look like slowing then start to brake or move out of the way.
One near me I approach up a steep hill and there’s a junction the other side of the pinch point so me and car are both approaching slowly, I’ve just held my line and ended up both of us stopped, me shouting at the driver for not giving way, driver shouting at me for…well just for being on a bike really.
Blatant bullying tactics like this really gets my back up so aslong as I consider it safe I’ll stand my ground and argue the point.
Oh also had an incident near skipton last week, very narrow NSL road, me in primary, approaching vehicles slow, I get out the way, vehicle passes at reasonable speed, everybodys happy. Apart from one grey haired woman in a blue pickup truck, kept driving straight at me without slowing down, I got out of the way sharpish.
