The interest in, and competition for, hands-free driving is heating up as General Motors (GM) - Get Report is debuting the 2018 Cadillac CT6 this fall, which is its answer to Tesla's (TSLA) - Get Report autopilot mode.

The CT6 features what it calls Super Cruise (see video below), which offers hands-free driving on the highway. The feature uses both a driver-attention system that scans the driver's face to make sure he is focused on the road, combined with a LIDAR mapping system, which measures distance to a target by lighting it with a laser light, in addition to real-time cameras, sensors and GPS.

The add-on cost is $2,500, and it is available on the CT6 Premium Luxury and CT6 Platinum trim levels this fall.

According to a Cadillac promotional video, in front of the wheel of the CT6, you can be either a "driver," by simply driving the car, or a "supervisor," by programming the Super Cruise function.

In spite of the growing popularity of hands-free driving, it is not problem-free. Fatalities have occurred in accidents involving Tesla's autopilot, including one in Florida and another in China. The National Highway Traffic Safety Administration determined in the Florida case that the driver, not Tesla, was at fault and there was no need for a recall, according to The New York Times.

Tesla could not immediately be reached for comment.
