This reorganisation was both unfair – only one in five families even owned a car – and cruel: urban residents had been denied the opportunity to enjoy the city's simplest daily pleasures: walking on convivial streets, sitting around in public. And playing: children had largely disappeared from Bogotá's streets, not because of the fear of gunfire or abduction, but because the streets had been rendered dangerous by sheer speed. Peñalosa's first and most defining act as mayor was to declare war: not on crime or drugs or poverty, but on cars.
