Well theoretically anyway. That's what they seem to do in places where
the 1m min is in effect. At the moment here it's up to the driver to
determine what a safe passing distance is. 1 meter minimum is better
than that, I think.

Depends on the road.

Many years ago, I got blown off the road by a passing truck. I don't
remember for sure, but it may have given 2m of clearance, but certainly
not more than that.

In this particular situation, I was on a right-hand bend, the road had
minimal paved shoulder, and a double-yellow center line. Because it was
essentially a blind curve, the truck had near-zero incentive to give me
anything more than the absolute minimum space.

For me getting blown off the road, that was partly that I was really
fatigued, and it probably wouldn't have happened, if I had been in
better condition.
