In the mining dead PVP enabled, you're supposed to be fighting walking dead style, maybe with friends and having some wars. In the mining daed PVP disabled, you're supposed to make friends, survive the walkers and elements and role-play. Maybe instead of having some stranger inside your car be able to take out your engine in three seconds is a little op, and someone being able to destroy your car with four bullets is a little extreme. Maybe in PVP you should be able to take out an engine and destroy a car that fast, but in PVP Disabled there's really no purpose of destroying a car. I think that at least cars should have a small buff in PVP disabled, so that they can withstand ten bullets, or maybe it takes players ten or twenty seconds to take out parts from your car.
