There's a lot of "I MUST OVERTAKE THE CYCLIST IMMEDIATELY" attitude being displayed in this thread with comments like "Sometimes I can only give 30cm space". How about waiting behind... like you would with a car on a busy street?
On that road I wouldn't expect anyone to be overtaking a cyclist unless the cyclist had waved them through and even then I would only really expect a cyclist to wave you through at the passing point.
What would you do if it was a horse in front? Treat it the same way.

Note the car up the road, note how close it already is to the offside hedges, note how impossible it would be to give 1.5m, even if the cyclist stopped to let you past..

At the next junction, both would then get their highway code books out and slap each other with them.



if you can't deal with something as simple as a cyclist on the road then maybe handing in your license is the way to go.
