I'd recommend the youtube channel "Not Just Bikes", a guy who moved from Canada to the Netherlands. It's perfectly normal over there to do everything you said is unrealistic.
Imagine not having to chaperone your kids around until they're old enough to drive. In much of the US, this is unthinkable, and it takes a large mental toll on parents, but in the Netherlands, it's not uncommon for elementary schoolers to bike to and from school, friends houses, even riding public transit on their own.
In much of the US, your kids can be taken by social services for this, even if it was perfectly safe for them to do so. And even if it's legal to let your kids be fairly independent, it doesn't matter when you have to fight to get them back (very much "you can beat the rap but you can't beat the ride").
It's depressing just how far we've fallen under the guise of "protect the children".
I did all of these things when I was in elementary school in the late 70's, and biking without a helmet no less. Hours and hours with no adult supervision, biking all over town.
I even went to an theme park with my sister, without parents when we were 9 and 11 - took multiple buses to get there about an hour from my house. We got lost on the way home and didn't know which bus to get on. Somebody helped us and we were fine.
Can you imagine the outrage nowadays if such a thing took place.
Car travel with kids is way easier compared to other methods.
We took the kids to Paris a while back and carting the stroller up and down the stairs to the metro was a huge pain.
(Raised two kids from 0 to 5y and 7y without a car. Started splitting a car about 6 months ago when we had a third child. Lots of walking, double decker stroller, bus, subway, and bike trailer.)
I personally love driving. Since I was a kid, I always wanted to drive cars and even now, I enjoy the feeling of driving a car. One can argue about whether it's the best mode of transport, etc. but for me (and many like me), it's a pleasure of life.
Let's try to stop people from carrying assault weapons before we move to cars?
What comments express that "general theme"? Is it possible that's a preconceived notion?
Big brother / Tesla / Waymo will do your driving, will do it better than you. Just sit back.
Let's try to stop people from operating heavy machinery which kills many multiples of people before we move to guns?
Note: I am personally pro individual car and gun ownership, just wanting to show you an alternate take on your statement. Personally I'm way more likely to die because of an incompetent driver than someone shooting me, so if I really wanted to reduce the risk of harm coming to me I'd prefer if we made it way more difficult to operate a car in public.
