Today is Día sin carro (Car-free Day) here in Bogotá, meaning that all private cars are banned from the roads during daylight hours.

The scheme’s been running since 2001 and by most estimates should take 1.5 million vehicles off the roads. While that excludes taxis and buses i.e. some of the more dangerous drivers and noxious vehicles, respectively, it must have a significant impact on overall levels of airborne nasties choking the city’s 9m residents.

A great idea: if only for one day.

Once a week would be a worthwhile experiment, but I suspect affluent/influential bogotanos‘ aversion to the oversubscribed public transport network makes it less than likely.
