Driving is often an unenjoyable experience because I'm a control freak and people are idiots and there are cops.  I was noticing recently that most of my driving is done at or around mealtimes, such as commuting to work in the morning, driving to get food around noon, and commuting home from work in the evening.  Since I'm like an infant when it comes to food (i.e. hungry = cranky), it's pretty easy to see a correlation between driving-induced anger and mealtimes.  I should always eat before I drive. #travel
