The Houston Metroplex is nearly 10% the area of the entire country of Italy. The former essentially didn’t exist before automobiles. The latter was laid out for pedestrian travel. So, I don’t get your point... why would you expect to find anything comparable between a city in Italy and Houston? Are there towns in the US where everything is within biking distance? Of course. Hundreds — maybe thousands — of such towns and villages; indeed, far more in the US than in Italy.
