The parking to the passenger side technique only works well at places like work. In any other setting, it wouldn't work. You also have to take into account how well the person is parked. If you park too close, they can graze your car while backing out.
Another factor to take into account is the side of the door. Usually, you want to stay away from parking close to the passenger side of an SUV, truck, or coupe.
