In a cold climate that usually wouldn't be a problem, but when it's hotter out an open thermostat does actually still restrict the flow of coolant which allows the coolant time to transfer heat.

If you have enough cool air going across the radiator you can get away without having a thermostat. Driving down the street forces alot of air across the radiator, riding around slow with your idle cranked doesn't.

Some people with no gauges may think they are fine with no thermostat but may actually be running temps as high as 245-250 degrees, a good cooling system may not puke out any coolant below 250 degrees but that doesn't mean that temperature is good for your motor.
