Notice anything strange about these pictures?

Ok, how about no cars?

The government here bans cars for a day every few months. City of over 1 million people. No cars allowed on the streets today from 6am to 6pm. Hugh delivery trucks stopped at the edge of town. If you have an emergency you can drive, but it better be an emergency or you go to jail.

Interesting concept. People really take advantage of it. Kids on bikes, scooters, families walking together. Nice idea.
