Unmanned Vehicles Can Hurt or Kill

I have found that, for many vehicles, when they are pushed into, roll onto, or are called on top of another player, that player can be hurt or instantly killed. The same is true if the vehicle is a personal vehicle or the player has entered the keycode. This is true for the following, although I have observed the behavior across multiple wipes and individual ones may have been fixed:

• Scrap Helicopters: when called on top of a sleeping player, it will instantly kill the player it lands on. Additionally, I know (from experience) that when I have been piloting and jumped out before landing—or even after landing but still rolling—it is an instant kill. (This one I have been the most cautious to test, because it always results in player death. I have not tested this recently on myself, and I've only observed another player use the exploit to remove sleepers from a build area)
• Trains: when no one is on a train, but it is still moving (not confirmed recently- resulted in my own death by jumping off a train)
• Modular Vehicles: when the driver jumps out, when an empty vehicle is pushed, or when the vehicle is rolling down a slope (confirmed this wipe)
• Motorcycles: when a motorbike is thrown out of the player's inventory and rolls (confirmed this wipe) 

I am unsure about snowmobiles - I believe I was hurt by a "wild" one from artic research a wipe or two ago. I've tried to list only what I have seen or has happened to me in the past couple months. 

The scope of this bug is big enough so I was hesitant to disclose it on the forums publicly, and until this wipe, didn't know the full scope. After being mauled by my own motorcycle rolling downhill (the circumstances were bizarre), I realized this might just be a problem universally with vehicles. At the very least, players will know they are vulnerable to this sort of thing by bad actors who can quite literally "hit and run".
