Hiding the car
Now that you have a "no move" option, can you add a "no car" option. (This is already available as an extension.) The game already has a lot of meta elements (sun, licence plates, bollards, etc) but being able to tell a country by a piece of black tape on a roof rack is too much! Also, photospheres often have info if you pan down, so a car blob would remove that too. I know this won't solve every "car meta" issue /cough Nigeria/ but it's a start. Best wishes.
