When I drive home at 2AM, I have to come up with things to entertain myself.
So that's how i came up with "highway confessionals". Instead of keeping my worst actions and darkest thoughts inside, I just yell them out the window. The road is basically empty, so why not? Any higher power would probably be amused by my antics, rather than plain ol boring prayer.
You should try it, it's really funny. That is, if you have things to get off your chest
