I drive a 2021 GMC Terrain and there are a couple of new features (compared to the 2013 GMC Terrain that I traded-in) that I really like. They include adaptive speed control, where you set the maximum speed that you want to drive and the distance between you and the vehicle in front of you (in car-lengths) and it maintain that distance and matches the speed, as long as it's less than what you've set. I also like the automatic dimming high-beams. One thing I wish it had, that my wife's Mercedes C300 has, is automatic windshield wipers, which changes speed depending on how heavy it's raining. One thing that I wasn't sure that I'd like, but now that I'm used to it, I kind of like, and that's 'push-button' (actually switches that you pull) gear shift mounted in the dash. It allows for a 'cleaner' center console with more usable space for cup holders and a place to put your cell phone. Also, the automatic braking is handy, particularly when you're trying to navigate parking lots with people stopping quick or backing out without looking.
All-in-all, the additional 'tech' in my current car, compared to the same, albeit eight-year older, model, is highly appreciated and works really well.

Touch screens are great. My 2021 GMC Terrain is a touch screen and it works fine. I can also use voice commands to enter things like addresses in the navigator and so on. However, my wife's 2018 Mercedes C300, it's not a touch screen and no voice command. It's a pain having to use a 'knob' in the center console to 'type' in addresses or select options.
