This question was closed on option A with a closing date of 9/29/2016. On 29 September 2016, California's governor signed a bill into law which permits the use of autonomous vehicles on some state roads (Road & Track, East County Today, California Legislative Information). Most states neither explicitly allow nor explicitly ban the operation of autonomous vehicles on public roads, making such vehicles de facto legal (Washington Post). However, several states are considering legislation that would explicitly allow autonomous vehicles to operate on public roads (National Conference of State Legislatures, The Center for Internet and Society). Autonomous vehicles are those that can operate without the active control or monitoring of a human driver, at least under some conditions. This does not refer to cars with regular features such as adaptive cruise control, lane assist, crash avoidance, emergency braking, and other technology unless those features allow a driver to cede all control and monitoring. Any legislation enacted allowing autonomous vehicles on public roads will resolve the question as "yes," even if the legislation places restrictions on those autonomous vehicles (e.g., by limiting operation to certain roads or conditions, or only allowing operation for the purposes of research or testing).
