an EV charged from fossil electricity saves only 33% on emissions compared to a fossil car

Or, stated more honestly, an EV deriving electricity from even fossil-based grid-scale generation uses roughly half the raw combustables as an ICE with the added benefit of emission scrubbing.

if i am paying 40k$ for an EV i am expecting my purchase to act as a contribution to safeguard the environement

We are fortunate, then, that this is already the case.

EVs are a pass for me for now but thats my opinion.

I'm not sure how you've determined they should be a pass - if you're comparing like to like and comparing to new ICE vehicles of similar capability, there's no reason not to go EV for most people.

But sure, it is a matter of preference.
