> There are different kinds of highways here: interstate (numbered highways that cross state lines, with the exception of I-4, which is entirely within Florida), There's actually a lot of interstates that aren't interstate. Not quite sure how that got started. Aside from perhaps a dozen "primary" interstates that aren't interstate, most of the "auxiliary" interstates are not interstate. > a highway differs from other roads (sometimes we call those "surface streets") in that it has controlled or limited access and is "maintained" by a government agency of some kind. I am a little bit curious as to where you're from. :) In my experience (a little bit of California, a lot of the south and eastern seaboard), controlled access on state highways is the exception rather than the rule. Usually the best case scenario is that you get no stops for the non-highway intersecting roads (they simply stop and make a turn or cross the highway when there's no traffic - obviously this only works on the rural sections) and interstate-style merges on major state highway intersections. In more built up areas stops tend to be frequent. I'd like to drive where you are!
