I used to see them a lot in a neighborhood where I used to live.
In such a case, they can be self-perpetuating. In your community, you see many of these every day and thus is comes to seem like a natural way to memorialize someone. Then a loved one of your own dies and you go with a similar memorial.
I will say, however, that I grew to dislike them for some nuanced and touchy reasons.
In this neighborhood, these memorials almost always named young men- died late teens or early twenties. Of course I can’t make fair assumptions about any one particular person’s death but, in general, given the problems with drugs and crime and gang related activity in this neighborhood, I definitely believed that most of these young men were dying while involved in gang activity.
Now, I don’t believe in fate but I do believe that common human behavior can often be fatalistic- or maybe a better term is self-fulfilling prophesy. Living with a belief that something is going to happen, little choices we make along the way can serve to make that result come true. It’s more often than not our subconscious at play that leads us to our more self destructive choices.
I’m not saying any of these people set it as a goal to die by the age of 20. It’s not something they wanted, not something they considered a desirable outcome. But sometime around the age of twelve or thirteen or fourteen, looking at the tragic end that’s been met by the older neighbor boy, or the older cousin, or their own 19 year old father who died when they were a baby… I believe the seed gets planted deep within the mind that “I’ll probably be dead by age 20.” Once that seed is planted, it’s difficult to avoid taking steps to make it come true- especially if it gets reinforced on a daily basis.
The pervasiveness of these memorial decals can be just one more reinforcement of that prophesy. Not only a reinforcement, but actually a means of glorifying the tragic end- “My mom will probably have one of those on her car for me someday”. Again, not something that’s wanted but something that someone’s come to expect for himself. We’re not talking about a community with access to decent counseling for troubled youth.
So, yeah. I grew to dislike these things and they’ll always have a negative connotation for me. Not that car decals are the root cause for young men dying in criminal activity but I really have come to see it as being among the “nexus of contributing factors” as it were.
