This got scrambled first time. A potential, and eventually actual buyer, wanted to see the house and Mom's Taxi was not home, so I loaded our Springer Spaniels in the back seat and away we went. Lillie tried to climb into the front seat, but I explained that she could not drive and she lay down in the back. Both girls calmed down and saw quietly in the back seat, without sedatives, sometimes looking out the window. I explained to my wife that Rosie and I could split driving shifts. She was not convinced. The first prairie dog or pronghorn antelope along the road and we would driving after it.
The more I drive my CT5, the more impressed I get with the electronics. The SuperCruise lane change capacity at first disappointed me. I turn the turn signal on and I have to turn it off after the lane change completes.
A few weeks back, I watched a YouTube video about features present in many cars that are not explicitly in the manuals and are very nice. One is that on many cars, if you turn the turn signal stalk just a little, it turns on the blinker just long enough to warn those in that lane, "I'm coming over." (In the 1960s, I repaired the blinkers on my 1964 Chevy Malibu wagon, and saw the very curious mechanism to implement that in plastic, without electronics.)
So I did the brief warning mode. SuperCruise did the lane change with no need to turn off the blinker. Very nice. It also will do uncommanded lane changes to get around road hogs. I do not understand how it makes this decision but it is possible to tell it to not make uncommanded right lane changes, I have never seen it make a dangerous decision on this.
