I'm an aging millennial, but on a purely personal level, when I lived in a city with good public transit, I was a lot happier, most of the time. I really like stepping off the train and the bus and being on my own two feet, the walking exercise, not being chained to this thing I have to worry about. I hate driving, I hate parking, I hate owning a car--the maintenance, the ongoing cost of fuel and insurance, all of it…
Absolutely no question, living in the city (in this case, Manhattan/NYC), a car is a liability. Parking was either insanely expensive or a game of musical chairs 2X per week as the no parking times for the streetsweepers come up (and that was decades ago).
But anywhere else, the car is basically a necessity. Doesn't have to be fancy, but it does have to be. I keep looking at electric motorcycles/scooters for a relatively short commute, but not keen on the hazards (and I'm not risk averse; I've had sportscar racing licenses & experience, rock climbing, etc., but when surgeons I know call motorcycles "donor-cycles", I take the hint).
What is sad is that only rarely is driving fun anymore. A long drive in the country on a nice day was a real joy, but there's just too much traffic now...
