The whole thing stems from too many party goers using this product and then leaving the aerosol can in the street. I understand that there were literally thousands of cans the next morning and the city finally had enough and enacted the ordinance.

I can only imagine what it's like to run over an aerosol can - could be a improvised explosive device, of sorts..

At any rate - that's the "why" behind it..
