Problem with Raycasting a Car on a Moving Platform

So, currently my platform can only move the character on the platform, but since my game is involved with cars, it doesnt move the car with the platform, how could my code work with my car?

Script is located in StarterCharacterScripts

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local player = Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()

local Function

local lastPlatformCFrame

	local function onCharacterDied()
		Function:Disconnect()
	end

local function onHeartbeat()
	local rootPart = character:WaitForChild("HumanoidRootPart")

	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {character}
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude

	local raycastResult = workspace:Raycast(rootPart.Position, Vector3.new(0, -50, 0), raycastParams)
	if raycastResult and raycastResult.Instance.Name == "Platform" then
		local platformCFrame = raycastResult.Instance.CFrame

		if lastPlatformCFrame then
			local rel = platformCFrame * lastPlatformCFrame:inverse()
			rootPart.CFrame = rel * rootPart.CFrame
		end

		lastPlatformCFrame = platformCFrame
	else
		lastPlatformCFrame = nil
	end
end

character:FindFirstChild("Humanoid").Died:Connect(onCharacterDied)
Function = RunService.Heartbeat:Connect(onHeartbeat)

The car is called “Car” in workspace
