[Tagging] Maxspeed

[Colin Smale]

That would depend on so many factors, including wheelbase, overhang,
width, driving skill, weight distribution on individual wheels, even
speed.. Google for "swept path analysis"....

A passenger car or a delivery truck would be able to turn the corner, but a tractor-trailer rig (heavy goods vehicle) or bus would get wedged in place.

Where a road goes under a bridge, where do you measure the "height" of the road? The highest point (not good enough for vehicles) or the "lowest highest point" or "in the middle of the road"? I would expect maxheight:physical to apply to a "normal vehicle", of maybe 2.5m width.

A standout problem regularly occurs in Oregon where you can have human powered vehicles up to about 3 feet wide legally, but many cycleways, particularly older ones built before the 1990s, have barriers that make all but the 10-speeds with drop bars impractical as negotiating the barriers that keep motorists out also prevent longer or wider bicycles from fitting. Similar issues exist on Oklahoma turnpikes, which commonly allow vehicles up to 11'6" wide, but the typical cash toll booth is only capable of fitting a 9'5" wide vehicle. Go figure.
