What I saw on my way to work today - Overgrown dust bunny

I am fortunate enough that I am on the freeway a short distance for my commute. This morning at the on-ramp at 1st Street and Highway 101, traveling at a stop and slow pace, I noticed an enormous dust bunny on the side of the road. As large as my car, it was actuality it was a rolled up piece of carpet which has split and exploded with tufts of material. It looked like the dust bunnies you sweep out from under the bed but gigantic.
