The creativity of Italians in parking their cars and scooters – on traffic islands, the pavement or simply in the middle of the street – knows few limits. But now police in the capital Rome have enlisted the power of social media to help them get to grips with the endemic problem. Citizens who spot illegally parked cars can alert a dedicated police Twitter account, @PLRomaCapitale. The police then reply to say when they have taken action – typically in a matter of hours.
