Updated! It uses a fuzzy check from the ward boundary to share bike lanes that are on the border, and it seems to be working pretty well! 40th & 48th bot have tons of those (Clark, Ainslie, Leland)
Been dialing this in a bit more with all of your amazing feedback, and now added in shared routes. With that addition, the 40th Ward has 13.8 miles in his ward, 7.8 built this year, and the 48th Ward has 11.9 miles, 5.7 built this year! (with Clark counting for each of them)
Feedback welcome!
