I'm not sure about your brown townogy about the weapons gaining those features. Those added some new gameplay elements (for better or worse), whereas a rotating steering wheel is just a gimmick.
Yeah im not entirely sure where i was going with it either.
You can always try releasing the car with the steering wheel, and direct everyone to a poll in this thread.
Maybe give options like;
•Love it, add it to all vehicles
•Like it, keep it
•It's ok, remove animation
•Hate it, get rid of it all
Then update V2 accordingly after a couple weeks.
