This was my first thought. When I learned how to drive, the rule was one car length per 10 mph. So at highway speeds of 70, that would be 7 car lengths of space to ensure enough distance to safely stop or avoid a collision. I see approximately 0% of people following this rule nowadays, and while I try to maintain it myself, it often results in a stream of vehicles merging in front of me and messing up my distance. Fun times.

Handy tip:

In the USA, the lines on a highway are 10 ft long, the spaces between them are 30 ft.

So, a line and a space are about two car lengths. It’s a handy way to judge how close you are to the car ahead. At highway speeds, you want 3-4 lines between you.
