Ending Car Dependence basically means move to a denser city, which you're never going to convince everyone to do.
People already live in the cities, there isn’t anything to convince them of for that. Instead we have to build transit that allows people to not rely on a car for their daily needs. Not that you can’t have one, of course. But walking, biking, and rail infrastructure need much, much more funding and then we can reduce how we handicap society with car-only transit.
The best thing the university does is add a COTA (regional bus system) ticket as part of the tuition price to get students riding the bus locally instead of driving as they inevitably try to do.
Unfortunately, the bus service once you leave campus is comically bad so everyone just drives, catches a ride, or uses ride-sharing if you ever want to actually do anything not physically on campus. There are a lot of low-hanging fruit that the city and region refuse to take. We could run a tram from the southside all the way up to Old Worthington along the same street and you'd hit all the most dense spots in Columbus and you'd probably eliminate a lot of driving, traffic, and deaths but instead they're spending tens of millions of dollars adding new highways.
Yes, it does. Go visit the Netherlands and you'll see the remarkable difference. Just because some people are biking on those roads doesn't mean you have anywhere near the bicycle trip share that the Netherlands does.
(Rural is a different matter, but they're usually left out of infrastructure in general)
I mean I suppose this is technically true. But as someone who was raised across a smatter of rural and sparse suburb and who now lives in/near dense urban areas - the urban areas are the ones having much more trouble feeling a sense of connection.
In all of the rural areas, everyone knew each other by first name, greeted each other, dropped by with baked goods. Were they dependent on cars? Yeah I guess. Feels like we missed the elephant in the room though
Furthermore, I'd venture to propose that this is not merely the case in the US. My family in Mexico City often use public transportation for work, but frequently drive to visit each other on weekends because that's much easier.
