Memorials: Rolling With the Dead

It hasn't reached the popularity of the memorial t-shirt, but the rear window remembrance of the dead seems to be picking up speed. We've noticed it recently on cars ranging from this DC ghetto rod to a North Carolina white guy SUV. Not sure what we think of it.
If the dead guy is the p.o. of the particular hot rod, or if the ride is your dead uncle's dream car, it seems like a fantastic idea. But for the majority of the motoring public, which views cars as on level with washing machines, it seems like not much tribute at all.
