Well first off.. power brakes and power steering are minimal... I have drivin several cars in my life without steering, and brakes I have had completely fail on me before at an intersection and I still stopped... I have a light weight manual with a good ebrake. In order to get this to fail the computer would have to somehow throw a pulse with the application shut down and the card uninitialized to the proper output. Thats about as likely as your cd tray ejecting on its own... the computer would have to inadvertently send a pulse to the release latch.
