I use an Xbox controller with Linux. Only issue I ran into was a firmware update for the controller before it would work with Linux. I had to do the firmware upgrade through a Windows VM.
My guess is that they can kind of steer it by driving only the right or left side wheels. It's diesel electric so they could individually control each wheel motor.
