Been in Rome since Tuesday night and here are a few observations.
If the pelican crossing is on red it means you are in very serious danger if you cross the road. If it is on green it means you are in really serious danger if you cross the road.
If a policeman in white shirt and helmet is in the road peeping his whistle and stopping the traffic, before gesturing you to cross, you are still in really serious danger as the minute he turns his back the traffic accelerates on anyway.
The quaint traffic is just one of the reasons why Rome is such a great city.
