Answer: Walking is better than a car ride because walking has various health benefits, it does not cause air pollution, it does not cause noise pollution either, it does not contribute to traffic issues, it is the cheapest method of commute, and one is less likely to meet any serious accidents while walking.
Explanation: Walking has been counted in the best exercises for the body for ages. Doctors and physicians prescribe walking over using cars because walking helps regulate a number of functions in the body and also helps reduce excess fat. From the conversation point of view, walking should be preferred because it is environment-friendly. Walking does not leave a carbon footprint and causes no harm to the surrounding. More people walking would mean less vehicular traffic on the road, and ultimately more convenience in managing the traffic. Other than being healthy, walking is also 'safe' as a pedestrian is less likely to meet a deadly road accident than a car driver is. Moreover, walking costs way less than driving a car does.
