Step-by-step explanation:
When traveling at 50 MPH, the recommended distance between cars is typically 2 seconds. This is equivalent to about 7 car lengths. However, the exact number of car lengths can vary based on factors such as weather conditions, traffic density, and individual driving styles.
It's important to maintain a safe following distance to allow for enough time to react and stop safely in case of sudden braking or other emergencies. Keeping a distance of several car lengths helps ensure a safe driving experience for everyone on the road.
