I travel a specific two lane road to and from one of my rental apartments. It's about four miles long and is well paved for most of the stretch with a single traffic light at about the middle of the journey. The road is a single lane in each direction with no passing capability for the entire stretch..........rightly so because it rises and falls and has some slight curves.

I take the Dodge B-250 with all the tools and parts on this road and I always drive at +5...........45 mph. The limit is 40. Anything faster is totally unsafe for the B-250, especially at night.

So, my question is simple:

Why does a DB follow the van at a distance of 25'..........every single GD time that I take this road?
