This could be very controversial but.....
If Hitech would program such that when stopped, while hiding your vehicle under or in a certain amount of trees or brush, will disable your red Icon from being seen by enemy aircraft. You would have somewhat of your wish. Either some amount of contact with the brush or a minimum of two trees close together that you pull your vehicle under between them. Once you start moving, your icon lights back up. So watch your peddle calibration for spikes.
From an IL2 and Ju87-G2 perspective, this would cause many pilots to loose track of their target and even cause them to give up searching. As is now, I can keep an eye on my targets under the thickest trees because some part of the red icon always shows through. Giving GV's a way to hide that disables the icon from the air would remove some amount of frustration about being bombed. Heck even make it happen if the GV hides under the supply truck bridges or the town bridges over the moat or in a barn. Even that tower in town with the drive through arch at it's base.
In theory this would make it harder for low level carpet bombing right off the end of the runway against the spawn. Or, the Storch and GV's would have to work together with the bomber pilot to lay out smoke in meaningful ways. I've lain an orange line of smoke once for a 10k carpet bombing against a spawn. I got shot down but, the buff box I called in wiped out most of the GV I marked with their bomb carpet.
