"Car is here, btw, and W has no problem with it."

STOP mentioning if W is okay with something. You wanted the car, you got one. End of discussion.

"She said "well, we'll continue to walk a lot", and I, "yes, I've grown used to it and like it", and all was peace. "

And STOP agreeing with her point of view all the time. I don't think I've seen a post where you actually told her 'no' about something and stuck to it. You sneak around her to do certain things, but you never say 'NO'.
