EV's are boosted the cheaper you make electricity and/or the more expensive petrol is, so I suspect they will take a hit while electricity prices are already high and petrol prices afaik aren't doing anything crazy
Dunno. Mild hybrids don't really count, IMHO. If your car doesn't plug in, you get all your energy from fossils. Yeah, you can save some in a battery for later, but if none of that comes from the grid, there's no way to make it green.
