addEventHandler("onClientResourceStart", resourceRoot, 
    function()     
    end 
) 
  
function autonTila ( ) 
    if isPedInVehicle (localPlayer) then 
    sx, sy, sz = getElementVelocity (getPedOccupiedVehicle(localPlayer) 
    speed = math.floor(((sx^2 + sy^2 + sz^2)^(0.5))*180) 
    dxDrawText("Speed: "..tostring(speed).."KM/h", 1493, 839, 1550, 856, tocolor(255, 255, 255, 255), 1.00, "default", "left", "top", false, false, true, false, false) 
end 
  
function StopTheRender ( ) 
    removeEventHandler ( "onClientRender", root, autonTila ) 
end 
addEventHandler("onClientVehicleExit", root, StopTheRender) 
  
addEventHandler("onClientRender", root, 
    function() 
        dxDrawText("Speed: "..tostring(speed).."KM/h", 1493, 839, 1550, 856, tocolor(255, 255, 255, 255), 1.00, "default", "left", "top", false, false, true, false, false) 
    end

function autonTila ( ) 
    if isPedInVehicle ( localPlayer ) then 
        local sx, sy, sz = getElementVelocity ( getPedOccupiedVehicle ( localPlayer ) ) 
        speed = math.floor ( ( ( sx ^ 2 + sy ^ 2 + sz ^ 2 ) ^ ( 0.5 ) ) * 180 ) 
        dxDrawText ( "Speed: ".. tostring ( speed ) .."KM/h", 1493, 839, 1550, 856, tocolor(255, 255, 255, 255), 1.00, "default", "left", "top", false, false, true, false, false ) 
    end 
end 
  
function onEnterOrExit ( thePlayer, seat ) 
    if ( thePlayer == localPlayer and seat == 0 ) then 
        if ( eventName == "onClientVehicleEnter" ) then 
            addEventHandler ( "onClientRender", root, autonTila ) 
        else
