Why do I like to go on long drives even if I don't know where I'm going to?

I randomly get the urge to go on long drives thru Southern California, often to places I've been dozens of times already. I don't really do much when I go, just drive thru and go back home. Some of my friends said it's symbolic for me always "searching for something" like peace in my life that I cannot find. Often I get to the destination then can't wait to be back home again. Is something wrong with me? lol
