+Nissan has a hell of a challenge ahead of it with the GT-R LM Nismo and the custom tires created by Michelin will be a big part of the succes/failure equation.

Would you pay extra for a semi-autonomous driving system that still requires you to keep your hands on the steering wheel?

Like +Cadillac Super Cruise, +Tesla Motors AutoPilot and +TOYOTA's automated highway driving assist, the +Mercedes-Benz system will automatically follow the lane and maintain a safe distance to the vehicle ahead. While in truth, these are semi-autonomous systems with a limited scope of operation, some are calling these self-driving cars which in fact they are not. Mercedes is saying that the driver must keep their hands on the wheel while using the system or else it will disengage and other automakers are likely to do the same.
