I'd personally use the web editor at https://www.openstreetmap.org/
Make an account, go to the zone you want to edit and press the edit button. Add a line and once the line is added you can add a type to it (you can check the wiki if you don't know which one to use)
You can enable tracking on streetcomplete that will track your walk/bike/whatever and you can use that as a guide on the web app should it be hard via satellite (do note that this tracking is posted publicly).
I personally turned off the road width data as I always have to cross the roads and it both feels awkward and is just not that practical imo. But you can use any other measuring app if any exist to get the width and manually put in.
Tomtom Amigo also uses traffic data! Although their dataset is ofc smaller than google maps as less people use it. (Still not FOSS, but at least not google)
I think ideally the first xk should have somethong like 10% since there's still payment processing fees and such. After that have 30% then go down on huge amount of sales (to keep the big boys happy and on steam)
Imma just update: I have given up and wiped the drive to use it as a game drive for windows again. Each turn just gave hours of headache and I'm just done trying.
Installing Mint took over 3 hours of searching obscure errors with solutions that were way too technical. In the end having gone from 5pm to 11pm just to get Mint dual booting.
Got it installed and got teamspeak and stuff installed, after a bit too long having to find out but that's fine.
Spent 4 hours trying to get steam games to run, not a single working boot and couldn't find anything online.
I might try again once I get my new AMD based game pc whenever I have budget for it. But for now, nah this took too long and took way too much effort. I just started a new work project which has already been exhausting and I just plain don't have the energy to bother with this. Its not plug and play like people like to say online.
I installed mint yesterday and am having a PAIN installing anything not in the software manager. Currently stuck on teamspeak as my first thing to try. Got a tar.gz and can't find anything well explained online (as of yet, it was already 3 hours just to get mint to dual boot and I was exhausted)
