It is suggested to be one car length, or 20 feet, for every 10 miles per hour when you are driving. So, if you are driving at 50 mph, you should be 5 car lengths or 100 feet away from the car. This allows you to react and stop in time to avoid any accident. The 3 second rule is also suggested, where you follow the car in front of you by 3 seconds. This can be measured by any non-moving object: as the car passes it, count 3 seconds, and go.

Do people follow this? To some extent.
