His name: Antanas Mockus
In 1995 he was elected Mayor of Bogotá. Under Mockus’s leadership, Bogotá saw improvements such as: water usage dropped 40%, 7000 community security groups were formed and the homicide rate fell 70%, traffic fatalities dropped by over 50%, drinking water was provided to all
homes (up from 79% in 1993), and sewerage was provided to 95% of homes
(up from 71%). He had a reputation for honesty. When he asked residents to pay a voluntary extra 10% in
taxes, 63,000 people did so.How he lowered traffic fatalities: First, he painted the streets with 1,500 or so stars, each signifying where a pedestrian was struck by a car and ultimately died. But that wasn’t enough. So Mockus surmised that his constituents were not
motivated by fear of being struck by a car, but could be motivated by
embarrassment and/or shame. So he trained people to be mimes to
mock jaywalkers, and, amazingly, it worked.(Fact Source) Follow Ultrafacts for more facts
This sounds awesome and I want to fact check this later.
