When you're driving significantly below the speed limit (or more accurately, below the average speed of the other drivers), it becomes impossible to maintain proper dostance behind you. Add to that the fact that people randomly drive in the left/middle lanes regardless of actually passing anyone on their right and you're forcing people to brake, make dangerous merges, etc.

I know nothing about your driving, but I find (anecdotally) that drivers who drive significantly slower than traffic are also ones who never look in their rear view mirrors.
