Okay let’s clear this up. It’s vdm if u drop a car on somebody that doesn’t have a bomb on it. This is because when u drop the carbomb u have no way of knowing if the car hit u or near u because if it hits near u and u die due to the explosion it was because of the bomb which is fine. Now if it landed on top of u I still don’t think it should be vdm because u could make the same claim if a car hit the side of yours before it blew up from the bomb. It’s confusing but I don’t think it should be considered vdm
