ESKALATOR

Behavioral specialist Blaž Vršnik, Mh.D., also known as the PIDiatrist, is a fictional character whose mission is to make traveling on Prague’s public transport just a PIDi bit better. (PIDi bit is a wordplay – “pidi” means “tiny” in Czech, and PID stands for Prague Integrated Transport, the organization behind the project.) Through irony and humor, Blaž educates passengers – ideally without them even noticing they’re watching an educational video. This is the 17th episode, set in the Prague subway at Jiřího z Poděbrad — one of the deepest stations, and fortunately free of advertising.
