If you wanna go to garage map, go to: THE PLACE THAT YOU INSTALLED GAME IN THERE/Beamng.drive/content/levels/garage then open info.json file, then in the last line you'll see this: "hidden": true You can change the true to false. Then you can play in the garage map
If you did this: The map should appear in the freeroam map selector. If it doesn't appear, you did something wrong.
This is interesting stuff, I wonder if they're making it more like Street Legal/Revhead where the interactions with parts are more direct, rather than through the parts menu. Would tie in nicely with career mode, especially since we probably won't have access to the parts config/vehicle spawn menu like we do in Freeroam.
