Belgrade to make public transport free from January 1

First time it ever occurred to me, but now that I've read it, of course! Why wouldn't every city make this free?! Solving transportation woes is a surefire way to stoke your economy, and removing payments is going to make public transportation more efficient and cheaper to maintain (no ticket kiosks getting vandalized, no payment processors to pay). Seems like a win win for any congested city.
