This is a long thread of people talking past each other. The bottom line is simply this: if you want to drive with a larger-than-average following distance (call it whatever you want, a safety buffer, a "proper" following distance, the point is it is a distance less than the average following distance of the other drivers on the road) then you have to accept that you will not be able to drive at the same speed as the other traffic on the road. It's physically impossible. It can be psychologically frustrating because you see all the cars around you moving at X mph but your self-imposed constraints mean you can only make way at (X minus Y) mph. But them's the breaks, no pun intended

>It can be psychologically frustrating

True, though-

I like being a traffic hacker--come on in, plenty of room!
