I tend to disagree, the values you propose are more specific and not
universally applicable (this is not about speed, but about scale, these new
values would suggest to take into account other aspects like "visibility
from within a car on the street", not applicable in many cases).

I believe the originally proposed values are fine (besides the "house"
maybe"), they do give an indication about scale. I also think that
mentioning distances can generally be OK, given as an rough idea how to
read the values, but not as very strict limits. What is not OK are the
actual values: they seem off (too small) for what I believe is "street
scale", "area scale" or "within the building scale". It could also be
"small", "medium", "large" or "close", "medium distance", "far", but these
would give even less indication as to what scale it is about (they are
completely relative, without a point of reference, like street or building
do give), so the current proposal is better in that concern.
