It's not a bug. When you lose control of the vehicle, autopilot kicks in to avoid a crash.

The problem is that thing doesn't help to avoid crash. Usually it brings aircraft to crash. I don't lose control when I want to type in chat or open menu. This is unnecessary. That will be helpful if it would enable autopilot once player loses connection to server to prevent crash
