The terms used in this chapter mean:
(1)"Automated driving system," the hardware and software that are collectively capable of performing the entire dynamic driving task on a sustained basis;
(2)"Dynamic driving task," all of the real-time operational and tactical functions required to operate a vehicle in on-road traffic within an automated driving system's operational design domain, excluding strategic functions such as trip scheduling and selection of destinations and waypoints, including without limitation:
(a)Lateral vehicle motion control via steering;
(b)Longitudinal motion control via acceleration and deceleration;
