A lot of modern cars can be told to tie the presets to the key fob (it's a setting, not usually turned on by default).
If you open the driver's door with your key fob in your pocket, your presets are loaded and the seats and mirrors move to what you want. If your spouse opens the driver's door with their key fob, everything changes to their settings. If you have more than 2 drivers, you can buy extra key fobs at the dealer (expensive!!) and the car will keep track of settings for those too.
Sooner or later, those settings will not be tied to (or saved on) the fob, but your smart phone. Everyone has one of those in their pocket.
I found the car related announcements in Apple's most recent WWDC key note monumental in their reach. Many manufacturers signed on (notably except Tesla, Mazda, BMW) to support the next version of Car Play, which in a sense might reflect a surrender of the UX ownership:
