Re: They kinda do and kinda don't
"roundabout"
Wonder if they can handle a "magic" roundabout - like Swindon or Hemel Hempstead.
There was a peculiar one somewhere near Devizes. It was at the bottom of a steep hill. If you tried to leave at the first junction you faced a hairpin turn in a narrow street. The sign approaching the roundabout now made sense. It showed an arrow that indicated you went all the way round the roundabout first - a > 360degree turn - so you were then aimed nicely at the first exit.
Here is an interesting 'throughabout' in The Netherlands.
