HCD-14 Genesis uses optical recognition to identify the driver and initiate the starting sequence, while gear selection for the 8-speed automatic transmission is performed via paddle shifters.
Instead of stepped gears like a conventional transmission, it has a fixed planetary gear, and changes engine speed by adjusting the generator electric load.
One possible use of this technology is to provide context information from the car, something like the engine speed has reached 2000 rpm, the parking brake has been disengaged, the transmissiongear is in drive and the brake pedal is fully off the floor.
