My car has offline maps and navigation. I don't really care for navigation, but I find the maps pretty handy. VW releases updates very infrequently, and I don't know for how long they'll keep doing that. Recently I wondered whether I could convert OpenStreetMaps into the format used by the car. Codex took around a week to do that for me, with some light steering. That project would no doubt have taken me months - maybe a whole year to do on my own, and I'm not fully confident I could pull it off as well as Codex did. I can pull the most up to date maps from OSM, edit them as much as I want, and they look great on the car. It's mind boggling to me that we have this tech.

Does the car not check a signature or anything like that? You can just use any selfmade data?

It does, but someone leaked valid encryption keys on GitHub a few years ago (Codex found them).

		Love that, I have similar desires to be able to control some climate controllers so I can get a more native bluetooth connection to it and override their programming for fine control of devices and have it never phone back home. One of these days I'll have time to throw an LLM at it, but I've been working on a dead project for 4 years ago I dropped because I realized how daunting it was going to be turn it into a product, but now I've made progress that would have taken me a year, in a few weekends.
