Given that some places are dark, having a small flashlight in the free camera would be something very practical, especially to observe the details of vehicles when you are in the shade. Oh and if not, make the bushes less laggy, because currently when I go into a bush I quickly drop to 20fps when I usually have 80fps.
You could spawn walking mode mid air, turn on the flashlight quickly and pause the game But yeah that's excessive and there could be a flashlight for freecam too
