If you are lugging the engine (driving in too high a gear for the speed you are going) you will feel it the car will be totally unresponsive and may even "buck". If you are getting good throttle response you are not lugging the engine. Cruising at 1.5K to 2K RPM is fine. At crusing speeds you can never really be in too high a gear. Lugging is less of an issue with cars with a wide and flat torque curve (like a 335i)
