No you don't. The Mars map is exactly like the Earth map, with a Mars texture instead of the map, and a rover instead of an arrow. Technically you control where the rover goes by using the steering wheel, because the steering wheel controls where your car goes, and the rover's movements come from your car's GPS. But it's not the sort of video game you describe. There's no way it could possibly work as you describe. The steering wheel is mechanically connected to the front wheels and still steers the car even when Autopilot is engaged, so it could not possibly be used as a video game control.

The problem isn't my failure to disclose my opinion of the easter eggs, it's your misunderstanding of what they actually are.
