Really cool feature - the adaptive cruise control feature is now becoming an option on more mainstream cars, and it is one of those "how did I ever drive in traffic without this feature" things. I think many people don't get how incredible that feature alone is - it isn't fully autonomous, but it makes driving in serious traffic so much less stressful. Add in Tesla's auto lane change and lane keep and you're 80% of the way to self driving.
