Wow, cool!

I was actually silently waiting for someone to implement that feature.. ;)

But what about using turn restrictions instead of manipulating the
nearest segments of  the ways?

The reason is: if my destination is on side "A" of the bollard on the
restricted segment, garmin would still send me via the bollard whe
it's shorter because it ignores all restrictions if the destination is
within a restricted zone, right?

Thank you for working on this! :)
