Same problem in Canada. On some narrower roads the cyclist has to take up more road to force the drivers to wait until there is no incoming traffic in the other lane before overtaking. Otherwise some of them will try to squeeze through with zero consideration for the cyclist’s safety.

I’ve learned that in motorcycle riding lessons. You have to constantly defend your safety bubble. If you let drivers see a gap that looks big enough they will try to squeeze through it and will push you off the road.
