How would I make this define all vehicle seats?

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local player = script.Parent.Name
local PlayPlayer = game.Players:FindFirstChild(player)
local Sitting = false



humanoid.Seated:Connect(function(isSeated, seat)
	if isSeated then
		if seat == workspace.INSPARE.DriveSeat then
			Sitting = true

			while true do
				wait(1)
				if Sitting == true then
				PlayPlayer.leaderstats.Cash.Value = PlayPlayer.leaderstats.Cash.Value + 1
				end
			end
		end
	else
		print("The Player Stopped Sitting")
		Sitting = false
	end
end)

Hello, I found this code on the devfourms but I don't know how to how to make it define all of the vehicle seats in the workspace. I want to change this line of code:

if seat == workspace.INSPARE.DriveSeat then

Everytime i've tried to fix it it just gives an error. Please help!
