Some models of Russian GAZelle Next commercial vans and trucks have Tetris integrated into the instrument cluster as an Easter egg. Here's the Google translation of the YouTube poster's instructions of how to bring up the game:
1) Turning the ignition on 2) Start a car 3) Three times the right turn signal 4) Two times distant 5) Five times on the clutch 6) raise the speed to 2000 and at that moment we light the arrow to the left
