For those complaining that this game is not an idle game, most games don't work when the browser window is closed. It's idle because you can click them to do something continuously on their own while doing something in another browser window.
When you have a car in idle, or neutral, and have it running to play the radio, it will still work, but turn off the car and the radio shuts off for most cars. For most idle games, if you shut it off it will stop, but keeping it running while doing something else fulfills the idle part of the game.
Great game, but why does it keep saying that there is 2 or three humans instead of there are two or three humans? When there's more than one it's are, not is.
