Way too complicated. A loop even?

Look at Nero3D's post OP quoted.

Get the world angle from the player to the car (atan2 of the Player Pos - Vehicle Pos). Then get the player's facing angle (GetPlayerFacingAngle or GetPlayerCameraFrontVector + atan2).

Then you need to subtract the angles from one another, and clamp the value to [-180.0, 180.0]. The absolute value of that number is then the angle difference in degrees, you must then decide at which angle the player would be looking at/facing the car, and at which it isn't.
