Help. Get player names in lua

I have my own server. We have been working on a script that only let’s users on a list drive the admin vehicles in the server. We’ve gotten bits from other scrips and come up with some on our own and everything is working except being able to check player names against a list. if i take out the name part it disables the veh just fine. Can anyone help with the line and list please.

Citizen.CreateThread(function()
  while true do
    Citizen.Wait(0)
    local ped = GetPlayerPed(-1)
	local name = GetPlayerName(PlayerId())
	local veh = GetVehiclePedIsUsing(ped)
	local model = GetEntityModel(veh)
    if name ~= "john" , "kira" then
      if IsPedInAnyVehicle(ped) then
       local car = GetVehiclePedIsIn(GetPlayerPed(-1), false)
         if IsVehicleModel(car, GetHashKey("admin",_r)) then
		  SetVehicleUndriveable(GetVehiclePedIsUsing(ped), true)
		    
	end
	      end
    end
  end
end)
