Think about it like this, 11% of Americans have ev's. Those people are the ones with large amounts of disposable income, and probably the ones you want to slow down spending from the most. So fuel prices straight up don't effect them.

You don't want to reduce people's ability to make ends meet directly. Instead, as most western governments, you need to play as the "invisible hand". no one wants the economy to slow down, so you have to do it in a way that looks like money laundering, but for an economic slowdown. "What's that? Banks are failing? Well they didn't hedge their risk properly." " a business lost money? While it looks like they should have prepared for customers buying patterns changing"

An unfortunate reality, is that this is the better option. Otherwise you end up with a massive crash, because the market, does. Not. Self. Regulate.
