If anyone is to blame it would be the person who put the paint in the garbage (which you are not suppose to do unless it is dried).
And the second one to blame would be yourself for driving through it.
You posted your message at 954 so I am guessing your garbage wasnt picked up much more before that. Even if it was picked up at 7 am that still isnt that much time to get it cleaned up. Sometimes you just need to take it as a lesson learned I guess.
