I have never used cruise control in all the years I've been driving in any of the cars I've owned that have it..... I feel the very strong need to be in control of my vehicle at all times. Even when cruising down the highway, interstate or expressway on a long-distance trip it is not impossible that a deer could leap in front of the vehicle unexpectedly or an accident could occur just ahead, in which case the driver needs to be in command of the car in order to prevent additional damage and potential disaster.
Throttle vs. brake, even with CC, you're still the same motion away from stopping, and modern automated implementations (ACC) regulate speed, distance, and generally come with emergency pre-braking systems as well. When you're driving down to The Keys, for a 400 miles on long stretch of open, flat 6-lane interstate 95, ACC (the automated flavor) is fantastic.
It's more just a bit of physical relief vs. relinquishing focusing on the task at hand. And even as someone who is __very__ engaged in driving, every time I get behind the wheel, I find it a nice vehicle enhancement.
I've never liked heated seats and when I've sat in someone else's car that has them I always shut it off once I realize that my seat is unusually warm.....I don't need that, thank you! Just feels weird to me.....
Do a remote start with the car sitting outside in single digit cold, and when you make it to the car, it's warm, seats are too, even the steering wheel, (side mirrors are defrosted), oh yeah, that's when that kind tech is glorious.
(FWIW, I drive around with the top down, heated seats on, in 60 degree weather, so at least my, umm, rear is warm
