Iowa Code § 321.518

A person may operate an on-demand driverless-capable vehicle network. An on-demand driverless-capable vehicle network may be used to facilitate the transportation of persons or goods, including transportation for hire as defined in section 325A.1, and public transportation. An on-demand driverless-capable vehicle network may connect passengers to driverless-capable vehicles either exclusively or as part of a digital network that also connects passengers to conventional human drivers who provide transportation services, consistent with chapter 321N or any other applicable laws, in vehicles that are not driverless-capable vehicles.
