I'm assuming they've tested this but if it's driving and something quickly knocks you off course (blown tire, big hole in road, etc) will it try to correct?
Eventually I'm sure it'll get to the point of throwing on the hazards, slowing, and moving to the shoulder. But today it is not equipped to handle damage to the vehicle.
