I've been wanting to do that for sometime. You beat me to it. BTW, "this is a prius" is a bit redundant on a prius.
Supposedly the Prius has a Braking problem, not unintended acceleration.... You could make one up that says "Sorry Officer, I blew the Stop Sign, because it's a Prius, and I was Hypermileing!
Yes, I am very aware of that. However, the vinyl sticker is not for me to read. It is for the average Non-Prius owner behind me, that is uneducated enough to know that the Prius doesn't have any acceleration problems (pun intended)
