Thoughts on adaptive cruise
Some thoughts on the adaptive cruise control, it's absolutely my favorite feature, but there are some caveats, in my opinion...
The adaptive cruise control works so well, it can be tempting to think of this as an autonomous or at least a semi-autonomous vehicle. I have been amazed to see the car slow down to a full stop behind a vehicle in front of me coming to a well controlled full stop, and then pick up and follow it when the car resumed progress [had my foot hovering over the brake pedal all the way tho ;-)].
But... however tempting it is to think so, this isn't a self-driving car, and you need to disengage cruise control before entering corners, and before entering town limits lest you find yourself traveling far too fast for the environment.
If you're initially following behind another car that's doing the right thing, it can be tempting to think your car "knows what to do", but it doesn't, it's just mirroring the sentient driver ahead, and your car will take off and go way too fast the moment they exit the lane in front of you. I think it's also prudent to disengage cruise when in thick aggressive traffic where people are cutting in and out between lanes or in stop and go traffic. I also like to run mine with a longer following distance to give more margin for system "thinking" and for my intervening if it makes a mistake.
This system is a great advance over old-style "dumb" cruise control and I am tickled to have it, but it's still just an advanced cruise control and it isn't foolproof. You need to be mindful of the system limitations and remain the executive in control at all times. There are some similar caveats in the manual, but these are my two cents! ;-)
