Yeah the tech is cool but the learning curve for some of us elders is a little steeper than for my kids. My wife's new Mazda6 has the radar controlled cruise control which is cool until the other day when I had it set at 75 and came up on a guy that was slowing for the reduced speed ahead. As we were both now going about 50 mph for several miles, life was good until he pulled to the right and the cruise decided 75 was the right speed. Totally my fault but still a bit exhilarating.
