Toyota made a pilotless vehicle Platform 2.1, which has one distinctive feature, two steering wheels.
Developers assure that such a solution is necessary for testing in those countries where remotely piloted vehicles are banned on the legislative level. Car system has two options: Chauffeur and Guardian. The first one is essentially the autopilot, the second one corrects user's actions.
Toyota claims that such a development will help their company improve the autopilot and make autonomous cars more intelligent.
