Spotting them isnt so much the problem, but remembering where they are when you roll in to attack. Atleast for me. But that's kinda fun though, its a neat challenge.
Something else I noticed, It does not seem to be "common knowledge" that a Parked GV can shows half icon range, and one parked under a tree (or in some cases against a hedgerow, shows no icon.
Thats good stuff if you're a gv'er
