Well my wife and I are both…
Well my wife and I are both just shy of 69 years of age. We recently traded in our Prius V which we liked a lot and never had any problems with however 8 years old and 194000km on it. We bought the Hyundai Tucson Ultimate PHEV as the Toyota Rav 4 PHEV is hard to get without waiting over a year and it's kind of a tired design now needing a revamp IMHO.
Well I in particular loved the Hyundai Tucson Ultimate PHEV because of all the driving assistant tech and infotainment tech etc. My wife also loves it although she was a bit overwhelmed by all the tech options.
We each have our own profile that adjusts the seats and mirrors, Android auto for me and Apple Carplay for her, both using Google Maps as default, with Waze as second option for navigation!
There is a lot to learn on this vehicle if you want to customize the tech and I set things up for myself and when I showed my wife the options, she asked me to set her dashboard and infotainment the way she would like it!
So it's talked a couple months now and we are very comfortable with our setups and really really love this Tucson so much more than our previous Prius V hybrid.
If your mom is up to it, maybe work with her to setup everything how she would prefer and she may grow into it? My Hyundai dealer has a 30 day change it for a different model if you really are not satisfied with the new car as well.
