I thought we were saying access tags like motor_vehicle are legal
access, not physical access. I do not expect emergency vehicles to be
excluded by legal access tags. IMHO, only if it physically can't fit,
set width/maxwidth:physical or maxweight or surface on the way. Or do
I have this wrong?

This however is a fair point.
