One of the biggest problems is Icon range, you can mostly see aircrafts unless you are around canyons, however with ground vehicles you have no choice but gamble......
Either way its fair for ground vehicles, you only ditch - far as perks are concerned the loss is not enough to worry about it, vehicle perks are FAR to easy to come by.
Aircrafts have to land on runways - GV's can land anywhere giving the situation is correct (nobodys home)
