If SUV drivers would expand their following distances, sudden maneuvers would be eliminated.
It's the same for semi trucks. We should stay 7-10 seconds behind the car ahead. In addition, always be looking ahead 15 seconds.
For cars, that translates to a following distance of 3-5 seconds and looking ahead about 10 seconds.
When doing this simple task, you can see everything that happens on the road ahead of you. Controlled stops and actually not rear ending the car ahead are the results.
