It is most likely that the thermostat is stuck open as indicated by these facts:
1. The car is slow to warm up. Cold water is constantly flowing through the radiator during the warm up period thus retarding the ability for the engine to warm up.
2. At highway speeds so much cold air is flowing through the radiator that the engine cools down drastically. A functioning thermostat will partially close to retard water flow and stabilize the temperature at the preset degrees.
3. City speeds will evidently allow about the right air/water flow to allow the operating temperature to approximate the correct place with the thermostat open.
