Hands free I would like to try, maybe even adaptive cruise, but lane centering we have on 2 work vehicles, and its really not that helpful in the real world. One of our vehicles moves the vehicle which is ok, the other simply vibrates and that is just trash for sure.
Here is my opinion on "adaptive cruise control"
Interstate travel, it is junk. Like I said in my previous post, you have ONE job when driving. I use cruise control mainly to stay at a certain pace. Fuel mileage is the primary goal.
It does also help a bit mentally and physically. Set it and you can stretch your right leg out a bit. Mentally, you dont have to worry about LEO granting you driving awards.
Adaptive cruise on limited access roads (Interstates) will get on the brakes at a good distance from the slower traffic in front of you. I hate breaking cruise, so I will time my passes where I can leave the cruise on.
A-CC will also make you mentally lazy and you will suffer from HGPS (hypnotic gas pedal syndrome) and end up zoned out on which ever slow driver in front of you.
Now, A-CC is fantastic in very slow and variable rolling traffic. I enjoyed having it on my Kias for this very reason. I did not have to worry about the idiots who think the pedals are either 100% to the floor or zero.
I used to have to go into downtown DFW a couple times a week (office crap) and it was great. I would set the cruise at 5 over and let A-CC do all the slowing and speeding up. Made the frustration of morons more bearable.
It did OK on surface streets, but once you hit the brakes, you had to reset cruise control, but still was neat to do.
Yes, I use cruise as much as possible.... even in the slow zones. I love going fast, but my DL and wallet are not on the same page.
