My excuse is that I just don't drive much. So yeah, money. The incentives don't favor me selling my good-condition low-mileage ICE for a used high-mileage hybrid, even though I do want one.

If the government passes a carbon tax (or just cuts gasoline subsidies) then the math may change and push me over.

But to avoid harming poor people, they'd have to atomically pass an increase in welfare while making gasoline more expensive for the middle class. So it's politically difficult.
