I think you're getting cause and effect mixed up. Save for a few petrolheads and train enthusiasts, people use whatever happens to be the most convenient method to get around. In North America, most cities prioritise infrastructure for private cars to such an extent that any other mode is almost useless
Since private cars scale badly, you want to encourage people to take other modes, but in order to change behaviour, the alternatives need to be attractive - cycle layouts that are safe, buses and trains that are frequent and reliable, city layouts that don't involve a long drive to buy food. You can't convince people out of taking the rational choice. You have to build it
If you really don’t like cars, you’ll find a way to minimize use of them.
If you really don’t mind cars that much you’ll make up stories about how if buses and trains and bike lanes were more attractive then people would use them more.
I guarantee that if every American city had an ideal bus and train system, people would still find excuses and reasons to justify driving their cars.
There is literally an example of a city with great public transport and 90% of people there use it exclusively. So most people will not make excuses but just use the thing that is easy.
