Hi Iain

I think that's how they should look. In fact that's how many do look - a 
local dead end road near me acquired the nick-name of the lollipop road 
by the local kids, because to us, that's what it looked like.

Yes! The more accurate the better.

Not sure how you're doing it, but remember it does need an extra node or 
way, just add the tag to the end node of the highway.
Could you give a link to your work?

Do these areas have them?
I'm not convinced that they make the map hard to read.
