Mystery Monday- Driving

Driving around in Florida, it is a mystery I make it anywhere alive.  I mean, if there is an old person who should have stopped driving 5 years ago, a lost person, a person who can't manage to use their cell phone and drive at the same time, a bus- city or school, or a garbage truck anywhere around, I am sure to get behind them.  Especially if I have a hot pizza in the car and want to get home to eat it.  What is mysterious to you today?
