I remember going on a trip when I was younger, and my (also young) friend was driving. At one point we got onto a stretch of highway and he met speed with a slow or speed limit vehicle like that, kept going for miles.

I don't remember what prompted it, maybe an aggressive driver we encountered somewhere and were able to block in, maybe just because it'd be funny. But I do remember he'd tell that story for years, and we'd laugh about traffic being backed up further than we could see. Looking back, such a jerk move. I didn't argue against it at the time, but now I'm half surprised we didn't get a ticket. It's kind of a safety hazard.

Come to think of it, that was around 15 years ago. >.>
