Registering speed in local direction

Hi, I suppose I should use “Inverse Transform Location”, but I cannot get my head around it:

I have a ‘hover car’ drifting around, and it’s OWN SPACE I’d like to know how much it is drifting to the sides.

I do not even think that I need anything fancy, since I’m already storing ‘previous frame world position’, so I guess if I could only turn that into some local space of current local-to-world, then I’d get a vector of sorts of drift, in local no matter how I spin in world.

I’m going nuts, any help would be highly appreciated, thanks :slight_smile:

Wow, this is insane, ‘UnrotateVector’! OK, solved it, this gives actual speed on X :slight_smile:
