Simple metal rails have popped up at some intersection sin the bike-friendly city of Copenhagen. Instead of teetering and balancing like a Port Fishington bike polo wannabe, cyclists are encouraged to rest a leg or arm on the unobtrusive double railings while they wait for green light. The discreet rails offer a viable stopping point for commuter who may be tempted to dodge traffic or zip through a red light, in turn, subtlety reinforcing safe cycling practices.
