Why is this Vehicle Script not Working?

So this script is supposed to make a vehicle's Parent be your character, and if you die, it will break the vehicle and remove it.

The script makes you the parent of the vehicle, but it won't break or get removed after you die. Can someone please help me?

Here's the script:

function onDie()
	human = nil
	script.Parent.Parent:BreakJoints()
	wait(3)
	script.Parent.Parent:remove()
end

function Child(c)
	if c.Name == "SeatWeld" and c.Part1.Name == "Torso" then
		human = c.Part1.Parent
		script.Parent.Parent.Parent = human
		human.Humanoid.Died:connect(onDie)
	end
end

function noChild()
	human = nil
	script.Parent.Parent.Parent = game.Workspace
end

script.Parent.ChildAdded:connect(Child)
script.Parent.ChildRemoved:connect(noChild)

As per a comment above, you could use a for loop to remove welds instead of using the BreakJoints() method.

Also, PLEASE don't use the Remove() method. Instances that are removed rather than destroyed don't get added to the garbage collection list, and this can affect gameplay.

Example:

local car = script.Parent

local function onDeath()
	human = nil
	local parts = car:GetChildren()
	for i = 1, #parts do
		if parts[i]:IsA("Weld") then
			parts[i]:Destroy()
		end
	end
	car:Destroy()
end

local function child(c)
	if c.Name == "SeatWeld" and c.Part1.Name == "Torso" then
		human = c.Part1.Parent
		script.Parent.Parent.Parent = human
		human.Humanoid.Died:connect(onDeath)
	end
end

local function noChild()
	human = nil
	script.Parent.Parent.Parent = game.Workspace
end

Break the joints of the car model as well.
