I know I'm a corner case on this, but there are two cases where our car life significantly improves your quality of life.
1: you live with ADHD: "Oh my God, I need to leave five minutes ago" scheduling method. To anyone who says, "You just need to be more disciplined about time," I refer you to the part about ADHD.
2: If your quality of life depends on activities that are more wilderness/far away from cities, such as hiking, astronomy, camping, bird watching, and don't include (actively exclude?) urban experiences that require amenities.
3: Friends and family live 30 minutes to 6 hours away.
I have no problem with improving bus service for people and getting them out of cars because that means there'll be more room for me to go to where I want to go when I want to go.
Successful transit means a very regular schedule and ponctuality.
Your first point does not apply to, say, Switzerland. Missed your train? Just wait 5-10 minutes. 30 if you're in bumfuck nowhere.
1. Makes sense.
2. This is why non-car-centric countries don't ban cars. If you're that kind of person (and not everybody is), you buy a car. You may not use it beyond these wilderness activities though.
3. Trains.
Living with ADHD also increases your chances of getting into a car accident substantially. I can't find the numbers now, but the increase is non-trivial and there are some clear mechanisms (inattention, impulsivity and risk-seeking behaviors).
ADHD is a big part of the reason I don't drive. I'm lucky enough to live in Berkeley which is very walkable with decent transit, and I would hesitate to move anywhere more car-oriented exactly because I have ADHD.
Why are you assuming that it's a binary A or B?
I want good public transport in urban areas as I don't want to take the car, but I still own one for many uses.
I hate it to be mandatory to live.
1: This "ADHD" issue is because you've never seen properly ran bus system. I used to live in big European city, riding bus to work everyday, and I never even knew the bus schedule. I did not have to. They would come every 15 minutes, or every 7-8 minutes during the rush hour. So I could just show up at the stop anytime and be sure that a bus will appear quite soon. Zero advance planning required.
Half of all dutch people own cars (10,062,194 cars / 17,904,421 people). The majority of people still ride bikes or take public transport to move around except when they need to take their car. For comparison, a majority of americans have a car (259,238,294 cars / 333,287,557 people). Note that the denominator includes children in both cases.
You're not asked to give up going to the wilderness.
Regarding scheduling, in my eyes public transport where the mean time between busses is not under 15 minutes is not public transport. Running after a bus is a signal that the frequency is too low. "I need to leave five minutes ago to take the bus I intended" should be followed by "if I leave now I'll be a few minutes early for the next one".
