Currently there is only three states white, orange, red, and it is never very clear what state your vehicle is in.
e.g. Your instrument icon is white in your heli but your hud keeps blinking, or your car is all white but it only goes half the speed, or sometimes the wheel indicator is orange but the car drives completely fine and other times your wheel indicator is also orange but the wheel is wrecked.
Solution: Add shades of the colors like lite yellow, yellow, lite orange etc. like it was in arma 2.
And the wheel indicator should be cut up in to 4 (or 6 if you are driving a truck) smaller bits (not making new icons for every wheel, just cutting up smaller kakes inside the WHL icon) so you can see the health of each wheel. Same could be done with tracked vehicles, instead of having 2 icons you can just have 1.
