Any plan that relies on humanity to collectively go through some kind of personal growth prescribed by you, the individual, is bound for failure. You can't force people to give a shit, and you'll have a hard time convincing the guy pulling tuktuks through the rain that he actually has a better deal than the local taxi drivers. And he's not even the guy you really need to convince. We can't even convince billionaires who supposedly believe in climate change that maybe there are alternatives to private jets.
If you really want people to drive less, the only thing you can really do is provide alternatives and hope people hop on board, which is how the car originally spread in the first place. Spoiler though, they probably won't in any scalable long term capacity, because despite their flaws, cars are inherently a force multiplier. They just let you do a lot more, and as long as that remains true, people will be willing to pay the price of ownership.
Imagine how nice it is to get home after the monsoonal cargo cycling, how happy you are to see the family, how nice they are to you drenched and exhausted, how good the food tastes, the cardiovascular perks.
With a car you carry your mood wherever you go, there is no hard reset. You correct your sensitivity to register signals the monsoon would "normally" drown out until everything becomes a stress signal and you need Prozac or Valium to deal with it.
Car owners can workout too of course but it's an entirely different game if you have to fuel it with discipline in stead of necessity.
