Recently it's been discovered that Smart Summon builds its path data using OpenStreetMaps data. Or at least there is a lot of supporting evidence that suggests this. Like this post on Reddit Smart Summon paths use OpenStreetMap data for parking aisles, intersections, one-way directions (otherwise it can go wrong way / through parking spots) : teslamotors As far as I understand the car uses OpenStreetMaps for any navigational data. So things like the speed limit it shows for a certain road is likely from OpenStreetMaps. Assuming that's correct then we should be able to contribute to OpenStreetMaps ourselves where we pick a few places in our region as test cases, and we get them updated. After updating them it should only take a Map update cycle or two before the car has the additional data. So my plan is to pick one place to add Parking lot data, and one place to fix a speed limit. Then sit back and see what happens. How long it takes to get onto OpenStreetMaps, and how long it takes to eventually make its way onto the car. But, I don't have any experience with OpenStreetMaps. If I can't figure out how to do it myself then I'll probably just bribe someone to do it. My hope was to find a few other people in the PNW to work with on this experiment. If I'm not able to figure it out I'll probably just end up bribing someone to fix a few areas that annoy me.
