Description (last modified by naoliv)

Could JOSM detect some unneeded only_* turn restrictions, like the attached example?

The left example is valid (since we have multiple branchs), while the example on the right side has an unneeded only_straight_on (ie, there is only one way to follow and we don't need a restriction to say the obvious)

This could be possibly implemented by counting the number of connected ways at the via node. If = 2 then probably it's unnecessary.
