I think there’s a word for it, but essentially false nostalgia. Gen. Z absolutely has a lot of nostalgia for things people say were great despite never experiencing it themselves.
I have never seen a car upshift on coasting. I know BMW is a fan of essentially putting the car in neutral when you let go of the throttle. But that is the only manufacturer I’m aware of that does that.
Depends on the car, some of them are smarter about it. I remember my dad's old pickup would downshift if it picked up speed while not touching the throttle, like when going downhill
I'm nostalgic for 80s music, but I'm pretty sure the only thing I was interested in when they came out was reading the Beano and seeing what games were on this months covertape of Your Sinclair magazine.
I suspect my actual nostalgia is of playing Vice City in my early 20s.
