I said it had never occured to me before what a waste of fuel races were.
Later in the day I was indulging in a nap (it was a day of indulgence) and as I was drifting toward slumber, I had a mental image of a crowd of car racing spectators. The image changed to that of an arena filled with a crowd of roman gladiatorial games spectators.
In my half asleep state, I was likening nascar and gladiator fights. Further thoughts brought the following: it’s still better to waste fuel than execute wild animals, slaves or criminals.
At which point, I thought I really needed to sleep.
