Place a tracked vehicle on VR map.
First try and get it to turn right or left using A/D keys, you should notice that they are now the wrong way around.
Now take it for a drive sometimes the keys sort themselves out and then get mixed up again.
Sometimes when you tell it to go forward it will turn 90deg before heading off in that direction.
Other times it just keeps turning left and right on it's own.
Getting the vehicle to jump or flip is hit and miss sometimes it takes ages and lots of different key strokes other times it does it after two or three.
