It'd be interesting to write an app that searches for ways with similar*
tags within a certain** distance across the planet.

* It would be very tricky to figure out what "similar" means. Same highway
tags? A certain number of characters that match up in the name?

** Distance might be tricky to fine-tune. I imagine most of the duplicates
are either exactly the same (distance = 0) or very very close.

This would also take a long time to run.

Sounds like fun! Let's do it. Any similar ideas?
