I have been using a Comma 3 in my 2017 Volt for just over a year. It works great but it is not true autopilot. It handles lane centering (lateral control) and longitudinal control (like the Auto Cruise Control in many cars) really well. It can also bring the car to a complete stop and then start moving it again as the traffic resumes which is great in stop and go traffic. It also has auto brake hold so when I come to a stop, I don't have to hold the brake pedal. I bought it second hand and the install took a couple of hours to run the cable from the back of the car to the fuse box and up to the Comma installed on the windshield. I miss having it when I drive my wife's car. When I replace my Volt, if the Comma is still a product, I will make sure the replacement car is compatible.
