Yep, me too. And, at least in mine, it comes on every time I start the car, so I have to remember to turn it off.
So do all the current systems have an "off" switch? Because I would certainly worry about situations like Tuco had. I could certainly see that leading to surprised people overreacting in either braking or steering. The closest I've come to it is a rental car I had a couple of years ago that had that adaptive cruise control. I didn't know about it until it started adjusting. Luckily it made it's first adjustment based on the speed of the guy in front of me so I could figure out what was going on, and it was a fairly smooth adjustment. The second adjustment was with someone passing me on the right, who I guess got too close to me. That freaked me out a little. I don't think it ever activated outside of cruise control in the couple of days I had it.
If the current systems have an "off" switch, I wonder if that will be the same with this new standard?
