I rented a new Chrysler 200 a few months ago and just when I thought I had the throttle figured out to where I could trick the transmission into not upshifting when I wanted it not to, upshifting when I did want it to, etc... it stopped working. It was a bizarre experience, like some sort of arms race or adaptive-difficulty video game between it and me, with my goal to actually control the RPM and its goal being to prevent RPM from getting out of its preferred small range no matter how increasingly erratic-seeming my throttle foot behavior became.
As a result, I am unable to develop any intuition about how the engine will actually behave in response to my inputs, and in a split-second dangerous situation will be unable to do anything useful.
It's advertised as "helping fuel economy" but all it really is is "adaptively learning to ignore the operator's inputs" which might be nice for the first few thousand miles a brand new driver drives, but seems outright dangerous afterwards.
I really don't know how people drive, let alone enjoy, cars with automatics these days. Paddle shift with dual-clutch autos might be loads better, but they don't generally have those on cheap rentals, so I haven't had much time to play with one.
My truck has three "memory settings". I can adjust everything the way I want it -- different seat positions, mirrors, etc. -- and save those in "A". My girlfriend can then get everything the way she wants it (she's much shorter and smaller than me) and save her settings in "B". When I get in to drive after she has been driving, I just hit the "A" button to have everything adjusted back to exactly how I want it.
It's very handy when you have multiple people who drive a single vehicle.
Modern cars will already learn about driving characteristics so they can better manage the car to match, but I don't know if they try to match individuals.
