Not quite sure what your issue is then.I gave up on the idiots a long time ago and either slow right down or stop. No issue on a straight part of the road as they can see you and you can see them. It is on blind bends when they cut the corner and are either on the wrong side of the road or very close to the middle of the road.
Obviously I am very cautious when approaching these blind bends as in addition to cyclist cutting the corner many motorists do the same. If another vehicle does hit you even though you are going at a snail's pace and the other vehicle at speed, you probably will walk away. Same cannot be said for an errant cyclist, but motorist will get the blame anyway.
By the way it seems that the 1.5m is not a rule, but a guideline as per the following;
give motorcyclists, cyclists and horse riders and horse drawn vehicles at least as much room as you would when overtaking a car (see Rules 211 to 215).
As a guide:
As said always good to obey guidelines anyway.
- leave at least 1.5 metres when overtaking cyclists at speeds of up to 30mph, and give them more space when overtaking at higher speeds
- pass horse riders and horse-drawn vehicles at speeds under 10 mph and allow at least 2 metres of space
- allow at least 2 metres of space and keep to a low speed when passing a pedestrian who is walking in the road (for example, where there is no pavement)
- take extra care and give more space when overtaking motorcyclists, cyclists, horse riders, horse drawn vehicles and pedestrians in bad weather (including high winds) and at night
- you should wait behind the motorcyclist, cyclist, horse rider, horse drawn vehicle or pedestrian and not overtake if it is unsafe or not possible to meet these clearances.
The 1.5m gap only applies to overtaking, but you don't have a problem with overtaking. And when coming the other way, on blind bends, you slow down anyway because thats the sensible thing to do.
Seems you are actually happy?
