LONDON, England - Boris Johnson cycles frequently and when you’re in his city, he wants you to do the same.  As the Mayor of London he’s introduced a hopeful plan aimed at making the streets of London more bike-friendly: Expanding biking lanes, creating a cycle hire program and raising awareness of cycle safety.

We equipped Greg Hall's bicycle with a flip-cam.

But when I ventured out to get reaction from pedestrians, couriers, bus and taxi drivers I discovered one major problem – they all battle each other vigorously on the narrow London roads.

Cyclists share lanes with double-decker buses, but say they’re frequently side-swiped. Black Cab taxi drivers say pedestrians don’t look where they’re going when crossing streets. And when I interviewed courier Greg Hill he described one harrowing road accident in which he was sent to the hospital with a back injury.

To get an up close view of what really happens on the road we equipped Greg’s bicycle with a flip-cam. It took him only ten minutes to ride out and come back with first-person footage of this road madness. This did nothing to improve my confidence to shoot a piece to camera while riding a bike – my helmet strapped on tightly.

Safety concerns are paramount with Boris Johnson’s transportation advisor, who we interviewed. Especially after he and the Mayor witnessed a truck smash into a car next to them – while they were on a cycling tour of possible biking routes!

What does it say about a city when the Mayor and his officials cannot safely take a bike tour? And what does it say about a city when a courier believes he is safer without his helmet because drivers are less aggressive with him?

It says London cannot be a true "Cycle City" until the bikers, drivers, and pedestrians get along, move along and do so without knocking each other out.
