I know its more likely to be a dream like hlf3 happening tho but it looks great in game and you can make a more downsized one that just only have engine, wheels, the addons , spoiler and general body sides like back front(something like that),also without data with just colors like red orange yellow and green
also here’s a reference picture of the damage hud i stole from forza horizon 4
When it turns on it will disable the money, part, credits and scraps ui but others stays same.(a suggested hotkey would be h or t so its not to far but not to easy to be randomly pressed by someone other then a cat)
Also it if really actually happens, i would suggest to have it be tested on the derby area and only have it in the settings-(advanced options)-and have the damage gui option in it so no random would open it and don’t know how to disable it.
