What we need as a civilisation is people wanting less of everything, but that's really hard. People take things as given and if you even suggest taking away those things they get irrationally angry and dig down even harder.
Not very hard; there are several spiritual traditions which emphasize detachment from objects, e.g. Buddhism. But unfortunately, Buddhist countries don't generally do well militarily because of the focus on monasticism/pacifism. India was majority Buddhist in 6-7th century and arguably that made them vulnerable to the Arab invasions. Similar case can be made for Tibbet.
But this always gets framed as changing the hearts and minds of regular people. Well my own prime minister was a bit upset that people were consuming less during the height of the pandemic. They wanted people to get back to “supporting small businesses” ASAP.
Economists say people have infinite wants and needs but really, in practice it boils down to a desire to constantly learn new things. The only reason why people may want an infinitely high amount of money ie. infinite wants is because there is no opportunity cost to holding money, humans really love having infinite free things and hate things that cost them something.
What's irrational about it?
Especially in this case. People are being asked to drive less, when driving is currently a necessity in their daily lives. Meanwhile the upper class is flying private jets around.
Being asked to accept less in that situation should make you angry. And it isn't irrational.
American and maybe Canadian society. There is nothing particular to humans that makes them car dependent, urban design, education and other such circumstances make them so. In some countries car dependency is the exception due to good public transit coverage (for commuting or longer distances with high speed rail).
Of course there's no silver bullet that will make everyone abandon their car tomorrow morning, but a lot of car trips can be cut with good urban design (including walkability, cycling, public transit), and for the rest that remain for whatever reason, EVs are a better choice, obviously. However focusing only on EVs and ignoring the rest is only opening another can of worms to replace the current one.
Not dependent in the practical sense, but I think we are somewhat genetically wired for something related to long distance travel and/or the means to do so, or at least to move at higher speeds than we can on foot. There's the love for horses in (mostly female) humans, and the way car purchases are made is not at all driven by practical considerations only.
Transformation can make us less dependent on cars and reduce their use. It won't remove the desire to own and fully control means of transportation.
Lithium for e-bikes, golf-carts, trams and busses, taxis, ferries etc. are needed for the non-car-based city vision too, and the reduction in ICE pollution actually makes cities a nicer place to live.
They both have.
billions of light polluters today is much worse than a couple of heavy polluters 100 years ago.
Now I don't think any of this will be enough to avoid a major catastrophe due to AGW. But it's also clear from experience that, between tech advances and social self-control, the former is far more likely to happen at scale, and thus have any meaningful effect.
Option B) Fundamentally reorganize human society

Option B has a poor track record.
