Probably not no secret that in Europe, good roads. I think that this statement can be attributed to Portugal. The roads they have really good, and generally, the traffic pattern is very well thought-out. At all verges, where pedestrians walk, are very elegant columns, which do not provide parking and sidewalks to call in drivers. Sidewalks, by the way, like the sidewalks, and generally all the streets of cities in Portugal lined with small pebbles. Some would say that is not convenient to walk on his heels, probably yes, but I do not feel much difference.
