I know these are very popular, but at first glance, it looks to me like, "People I've Run Over With My Car". Then once I see that it's in fact a caricature of your family, and that you have three children (one of whom plays soccer and one who likes to swim) and two dogs (one of whom chews a frisbee), I think to myself:
Why? Why do I need to know this about you?
I'm happy for you, but I'm not sure why I, as a fellow person on the road, need this particular information. I'd much rather know how many tickets you have on your record and whether or not you are currently on any medication. Can you please put this information on a cute little sticker in your back window?
