Tesla fanboys can be quite annoying, true, but I don't think actively killing them is a "right thing".
Why would they be? They're not playable when the car is in motion. I believe there's a car that has an HDMI input for that when the car is not moving
Putting Easter Eggs in ECU software is kinda ... reckless?
The display UI shows velocity, warnings etc so it's not a like a entertainment and navigation system. Why add useless software and the mandatory bugs too it.
