I feel it could be easily handled by making it an upgrade rather than just outright removing it. It's a cool feature but quite annoying as a muscle car owner myself. Maybe make it only for the cars that are equipped with a wheelie bar.
Edit: just finished reading other replies, if its not a feature that can be toggled then why not just live with it with a rule that it can't be abused. Although since it wasn't a thing from the beginning I don't understand why it can't be toggled since rockstar added later on. But I'm not into coding so I wouldn't know.
