Abstract
Aspects of the disclosure relate to controlling a vehicle in an autonomous driving mode. For instance, a control command identifying a steering control position may be received by a steering system of the vehicle from an autonomous driving control system. Orientation of one or more wheels of the vehicle may be controlled according to the steering control position. After receiving the control command, that the steering system has not received a valid control command from the control system for a first predetermined duration may be determined. Based on the determination that the steering system has not received a valid control command from the control system for the first predetermined duration, the orientation of the one or more wheels may be continue to be controlled based on the steering control position.
