Definition: semiautonomous vehicle

A car that can accelerate, decelerate and stop without human intervention. Semiautonomous vehicles may be able to keep in lane, and they may also be able to park themselves, but they are not self-driving. In most cases, drivers must keep their hands on the wheel at all times. As of 2018, most automobile manufacturers offer some semiautonomous functions as standard equipment or as options. See self-driving car and automotive safety systems.
