When the bus (in your example) runs on a hourly schedule, while your car is always there when you spontaneously need it, then that freedom is real and not just propaganda.
I did this type of commute before where I had to catch the bus to work, which was also once every hour, and the anxiety during my early morning routine to not miss the bus was crazy since missing it meant one more hour of wait, compared to the freedom of jumping in my car without a fixed schedule while also saving 1h/day of time compared to the public transit, the difference was night and day, not propaganda.
Now if I had a train/subway to work, where I could sit down, and it ran every 15 minutes or less, then yeah, fuck driving and public transport all the way, but nobody sits in traffic for fun, but because of all options for their commute, driving is the better option.
I have only one life on this planet, and it's much shorter than the planet's life, therefore I need to make it a good and comfortable one while it lasts not sacrifice it for nothing, while China and India keep lighting the planet on fire and my boss is chauffeured in luxury cars and has 3 vacation homes. You need to (have the wealthy) lead by example and sacrifice themselves too before you ask the same from the working class!
If you wanna save the planet, then first talk to China and India, talk to politicians and corporate billionaires with private jets and yachts making a killing from forcing everyone into office 5 days/week and dodging taxes so that cities lack funds for infrastructure, not to the working class keeping the world running and feeding their families.
Didn't you just say you can get around fine on the bus? Can't you just get a car if it suits you?
For me personally it's nice to have a car. It would certainly be tough if I had less resources and public transit would be more appreciated.
