Tie Dyed What ???

Tie Dyed Toyota 

Marching Ducks

Found this car on a restaurant parking lot a few days ago.  It prompts three questions.  Who would do this kind of thing and Why would they want to? Plus, I believe it is illegal in our state?  I have a feeling it is a little old lady because the car had handicap tags and the restaurant is known for having a large customer base of  elder seniors.
