Dirty vehicle writing

I was sitting behind a van the other day, from memory it has some lame message written in the dirt on the back "This model also available in white" the van was white..... but the word 'model' got me thinking, more examples of low quality can be here. But there is perhaps a possibility here to create an interesting temporary public art work ?

See the work of Ben Long here:























Richard Prince set to one side - i am thinking country and western lyrics, pertinent websites links and plain old provocation.

mmmm
