It's every cyclists nightmare: your back to traffic and someone, for any number of reasons, straying into your space and taking you out.
These two cyclists were lucky in a lot of ways. They were uninjured, thankfully, but they also had a camera strapped to the forks of the trailing bike. It captured the "quick as a flash" moment when a car, which has been located by police, took them out.
Bikers, has this ever happened to you? Any other close calls?
