Who's to blame?

It was a summery Tuesday morning. The man rolled out of his bed, washed his face and got dressed. Then he headed to the kitchen. After pressing the button on his coffee maker, he stood in front of the window and looked outside. "Another day begins", he thought. Then he sat on his chair with his coffee next to him and a pile of papers on his hands and cursed as he had to go downtown one more time to pay the bills...
...Later in that same day, he approached his destination, which was right in the city center. He drove around a couple of blocks, maybe more, and looked for a parking space. He found none. He couldn't use the parking space provided by the city, because it had a fee and he needed the money for grocery shopping or something similar. Finally, filled up with frustration,  he gave up the searching and decided to park his car right in front, without thinking about pedestrians and mothers with strollers.

Where he parked? On the pavement. 

New rules for parking?

...Much later in that same day, I passed that spot, saw the car and took a picture. My first reaction was angriness, but in a couple of minutes that feeling passed. You will say "How can you defend him?", well I'm not. What he did had no excuse. He could take the bus, catch a taxi, ride a bicycle or just walk. He preferred his car, OK. But the reason I won't taking it out on him is because it is not entirely his fault. It is the city's fault, too. The city encourages this kind of behavior. The city's cars are the ones you see violate the rules first and most frequently. So after some thought, I've decided. I blame both. Him for his decision to park there and not thinking of others, and the city for not doing anything about it.

Who do you blame for? What are your thoughts on this matter?
