Weird, the tweet was dated 2018-05-22 but the Youtube video shows easter eggs already deployed by 2018-05-23. I know all Tesla vehicles have automatic over-the-air updates but that's still surprisingly quick. Must be Musk playing around with his time machine again.
I guess you don't consider that a video game, which is a perfectly valid opinion. But I'd just wish you had made your first comment "I don't consider Tesla's interactive easter eggs to be video games" instead. That way you clearly communicate your intent and this whole needless bikeshed could have been avoided in the first place.
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.
