This isn't exactly about getting around on a bike, and it's only connected to riding a bike in Italy by a stretch of the imagination.
But there is a lot of urban sprawl, even in Italy (especially in Rome!) and there were days of biking the Appian way where all I saw was a bunch of run-down homes and industrial stuff along a lonely road through the Italian countryside
That's why this documentary on urban sprawl is relevant. I'm hoping for a future time when enough people are willing to ride their bikes as their primary transportation, there's good public transportation in place, and cities become communities where people want to live, instead of the wasteland that so many of them are now (especially LA!).
So if you're interested in biking as a way of transforming the world, you may want to check this out.
