The key difference lies in the concept of "common ground," which refers to the shared knowledge and awareness between the driver and the passenger. Passengers can see the driving environment and adjust the conversation based on the demands placed on the driver, whereas someone on the other end of a cell phone call lacks this context and cannot modulate the conversation in response to the driving conditions.
