You are driving through city traffic in rush hour. What are the effects of stop-and-go driving?

You answered everything correctly. In stop-and-go traffic, frequent starting and stopping causes your car to use more fuel and produce more exhaust gases because the engine works less efficiently and acceleration requires extra energy. These constant stops and starts also create more nuisances for other drivers and pedestrians, such as noise, vibration, and delays. So, all listed effects are true and important to remember for city driving situations.
