“The odds of finding yourself behind a slow-poke driver on a single-lane, no-passing-road vary proportionately with how pressed you are for time.”
–Murphy’s Law of the Road (or at least, my version)
“The odds of said driver having exactly the same destination as you — thereby maximizing the amount of time you’re stuck behind them — also vary directly with how late you’re running.”
–Corollary, Murphy’s Law of the Road
