I guess this goes back to the default values for a
region/state/country, but in Australia some states have it so that
it's legal to do U-turns unless signed otherwise, and other states
have it illegal to do U-turns unless it's signed...

Should we be tagging where it's allowed or where it's not allowed or
where it's signed specifically one way or the other?
