We already have some checks on lanes

But it's a complicated subject.
(An issues too https://github.com/osm-fr/osmose-backend/issues/115 )

As you experienced with the subject, can you propose a check ?

What means "left;left|right" ? And what can be wrong with this ?

Do you talk about the transit:lanes proposed feature ?

We do not already make inter lanes tag check yet, but make sense.

This one, at least, look easy.

You suggest to detect gap between a node and the local shape of the 
roundabout ?
After micro-mapping, this is micro-fixing !
