One example is the steer-by-wire system on the new Infiniti Q50, which eliminates the traditional, mechanical link between the steering wheel and the tires. (There is a backup system in case the sedan loses power, though the vehicle last year was subject to a recall linked to the system.)

The research firm said the key obstacles to widespread sales of autonomous vehicles are not technological. Instead, they relate to "liability, regulation and legislation."
