They don't even work like regular freeways.  You can't pass, and even if
you can, it's limited by oncoming traffic and onramps.  Freeways are dual
carriageway, fully controlled, grade separated and high speed; anything
that doesn't meet that shouldn't be tagged as motorway.

I generally consider the last junction with another motorway to be a good
place, though the first grade separated junction to be a good compromise.
