[Prevent Leaving Vehichle] Best Method?

The goal is to prevent a character from leaving a car they are put into. My idea is to prevent the player from jumping. Is this the best method? if not what is? My Scripts: Script A

local noJump = script.NoJump:Clone()
	script.NoJump:Destroy()


function CharacterSpawned(char)
	local noJ = noJump:Clone()
	noJ.Parent = char
	Delay(0.2, function()
		noJ.Disabled = false
	end)
end

function PlayerEntered(player)
	player.CharacterAdded:connect(CharacterSpawned)
end

for _,v in pairs(game.Players:GetPlayers()) do PlayerEntered(v) end
game.Players.PlayerAdded:connect(PlayerEntered)

Script B(Inside A, Local Script)

local h = script.Parent:WaitForChild("Humanoid")

h.Changed:connect(function()
	h.Jump = false
end)

THANKS!

TheDeadlyPanther was on the right track with disabling the player from controlling the character. Luckily you are able to completely disable player control and still allow them to drive a vehicle. The best way (to my knowledge) to remove player control is by disabling the ControlScript in PlayerScripts. Here's some functions to disable/enable players ability to exit the vehicle.

function disableControl(player)
	if player:FindFirstChild("PlayerScripts") and player.PlayerScripts:FindFirstChild("ControlScript") then --Checks if there's a ControlScript to disable
		player.PlayerScripts.ControlScript.Disabled=true
	end
end

function enableControl(player)
	if player:FindFirstChild("PlayerScripts") and player.PlayerScripts:FindFirstChild("ControlScript") then --Checks if there's a ControlScript to enable
		player.PlayerScripts.ControlScript.Disabled=false
	end
end

I would do one of these two:

1. Disable the player from controlling the character, i don't know how but you can google it or insert a free model.
2. Anchor player should work, I think.
