A lot of car companys have different gauge options for their cars. On a simple car you might get just a spedo and a fuel gauge. While more expensive cars show everything going on in your engine.
Do how about that?
In my opinion, it creates too much micromanagement and will clutter up the UI, with a tiny bump in gameplay value. Not sure if it could be a valuable addition as a separate option.
This stuff would be part of different interior packages for sure.
keep up the good work!
