Cars itself are actually only a small part of climate change. The major part of it is form construction, planes, and electricity. We can fix electricity with sustainable energy, fixing planes is a lot harder as of now. Fixing construction seems impossible for now.
We'll run out of time before we we hit zero. We are already too fast to break before the cliff. All we can hope for is a soft landing, and we need everything for that. Even nuclear energy (go 100% on nuclear!)
what they do is lure you in with unsustainable prices and once they got established slap you with real price. Because for the real price you wouldn't find it worthy in the first place. But now that you enjoy it it's more likely you'll pay more than what you might initially do
