Not a bad way of handling it, it simplifies it a bit more which in turn lessons the chance of a new user not knowing.
How many of the towns/cities would we want to include on the map at that level dont have a state highway running thru them?
Its still also based on the city layer showing as expected, it would however reduce the size of a city and may in some cases put the centre in the wrong place (eg. if a state highway is pulls away before the centre) but as long as its not a major discrepancy it probably wouldnt be too noticeable.
