I wanted to share something I built that might be useful.
BorderWait.today http://borderwait.today/ ulls live wait time data from CBSA and CBP and displays it in a clean, mobile-friendly format, that includes the car browsers (newer GMs, Volvos, MBs, Teslas, etc.), so it's actually usable while you're on the road.
The use case is pretty straightforward: you're approaching the border from either side and you have a choice of crossings. This makes it easy to see which one has the shortest wait so you can make a quick decision without digging through government sites (some of them got stuck in the 2000-s). You can either list the border crossings closest to you using your device's GPS, or browse through them all.
I would really appreciate your feedback and suggestions on how to make it better and more usable.
