The car already has adaptive cruise control and lane-keep-assist, but you need to keep your hands on the wheel. With the Comma, I can set it up on most of the roads I drive (local or highway) and it&amp;#x27;ll keep me going at the desired speed in the center of the lane (up to a certain max turning torque, which is a limitation on the Acura LKAS system - if you&amp;#x27;re in the Bay Area, it handles 101 just fine but will struggle on the 280).&lt;p&gt;I&amp;#x27;ve logged about 3k miles of autonomous driving at this point and wouldn&amp;#x27;t hesitate to recommend it if your car supports it, with the understanding that  it&amp;#x27;s a limited system and you still have to pay attention the entire time. Unfortunately, it seems like a lot of the newer cars have tighter security around CAN bus communication, so it may not be easy for Comma to continue to do their thing.</text></comment>
