I’ve had a lot of cars. You’ll know this if you bought my book, in which I detail most of the wonderful cars I’ve owned, and also my 2001 Toyota Prius. For those of you who have never had the chance to experience a 2001 Prius, I strongly suggest you do so immediately, and probably at your local junkyard.
In my time with various cars, I’ve noticed something: some cars wave to each other. What I mean is, you’re cruising down the street, you see another car of the same make and model, the driver waves to you, you wave back, and everyone’s day is a little better because of the entire experience.
