Guardstones don't keep the wheels on the road, they keep the wheels off the
building.  Your duck is a drake.

Seems plausible.

The rows of "guard stones" along roads are certainly a predecessor of guard

Maybe, but they're on the wrong side of the road.  They prevent the vehicle
veering into trees, which would be just as effective as stopping it going
further and do as much (or as little) damage.  A guardrail would be
on the other side of the road, to prevent a vehicle going over the cliff.

The English equivalent of the modern Lietpfosten appears to be
called "verge marker" or "marker post" (the bulkier ones are
called bollards) https://uk.glasdon.com/road-safety/reflective-verge-markers

I don't know the English term for Leitstein or even if we ever had such
things.
