Custom Controls on Roblox' Vehicle Seat

I had a look at this post:

and came up with this code

local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")

local player = Players.LocalPlayer
local playerScripts = player:WaitForChild("PlayerScripts")
local playerModule = playerScripts:WaitForChild("PlayerModule")
local controlModule = require(playerModule:WaitForChild("ControlModule"))

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")

local accelerating = false
local decelerating = false
local steeringRight = false
local steeringLeft = false

local function BindContextActions()
    ContextActionService:BindAction("Accelerate",function(_,inputState)
        if inputState == Enum.UserInputState.Begin then
            accelerating = true
        elseif inputState == Enum.UserInputState.End then
            accelerating = false
        end
    end
    ,true,Enum.KeyCode.LeftControl)
    
    ContextActionService:BindAction("Decelerate",function(_,inputState)
        if inputState == Enum.UserInputState.Begin then
            decelerating = true
        elseif inputState == Enum.UserInputState.End then
            decelerating = false
        end
    end
    ,true,Enum.KeyCode.RightAlt)
end

humanoid.Seated:Connect(function(isSitting,seatedPart)
    if isSitting then
        task.wait(2)
        --if UserInputService.TouchEnabled and not UserInputService.MouseEnabled and not UserInputService.KeyboardEnabled then
            controlModule:DisableVehicleSeat()
            BindContextActions()
        --end
        
    end
end)

game:GetService("RunService").RenderStepped:Connect(function()
    if accelerating then
        humanoid:Move(Vector3.new(0,0,1),true)
        print("accelerating")
    end
    
    if decelerating then
        humanoid:Move(Vector3.new(0,0,-1),true)
        print("decelerating")
    end
end)

Everything does work fine, except it doesnt move the car.
