I really liked this sticker initially because I drive sensible in a town full of reckless teens and college students and Im constantly getting honked at and my ass riden in my old Datsun.
I figured this would be a kind of "Piss Off" sticker to rude drivers and it would explain my driving style. The owner contacted my about my purchase along with some basic info about what he is trying to do. He said that there is a whole movement behind the sticker. Driving sensible is safe, better on fuel millage (great for my daily Datsun), and reduces stress on our vehicles.
My 280z isnt really preformance oriented so thats why this fit for me, I know alot of you guys like to drive fast and put in track time, but I also know of alot of daily driven 86's and I think just getting the word out can start this snowball downhill.
Here is a pic and the website.

The owner Fulton Hanson, has told me that clubs can get large order discounts. like 60 cents a sticker plus the shipping for the order.
Im just trying to get some exposure for a pretty cool movement and a sticker that I find pretty rad. will try to post a pic of my datsun soon!
anyone can contact him with order info at his email: fultonhanson@yahoo.com
