I'm sure those that have flown a helicopter, rather, sat on the pad for a good 5 - 10 minutes because no one needs supplies or transport, knows the annoyance of having to either hold down S to scoot back to your pad, or spin around so that you slide the other direction back towards your pad. It would be a huge quality of life change for pilots if the helicopters with wheels (can't recall if ones with skids did the same) simply didn't slowly roll forward while sitting on the pad. There's no real benefits to rolling forward while idle, only the con of being pretty annoying knowing you have to play a minigame if you want to stay on your pad.
Is it a possibility of having a way to lock the wheels? Imagine having to unlock them prior to landing else you goof up, but at least you don't have to worry about rolling forward while in base.
Though now that I think about it, it could just be something not exactly possible to implement for both wheeled/non-wheeled (if there are any non-wheeled that slide while idle) without it causing other issues.
Thoughts?
