Re: "three leading systems" WTF?
Technically it makes them a partly autonomous vehicle with additional remote controls, and probably manual controls nobody is using at the time.
Wierdly, quite alot of modern cars are, though the latency of their celluar radios make this impractical outside of Defcon demonstrations. If it has electric power steering and wireless data for the entertainment system/onstar/vehicle locator at least.
Thankfully this almost never happens.
