Remember Tuesday's video of the bicyclist being chased by a police car as fast as 60MPH? Even while it is possible to do in real life, this video wasn't real. It was a viral for a new Czech video site. This is how it was done.

Many cyclists—including myself—argued in the comments that it was perfectly possible thanks to a phenomenon called drafting. Any skilled cyclist is capable of doing this. The drafting world record is now at 268.8km/h (167mph), set by Dutch cyclist Fred Rompelberg in 1995. He beat John Howard's previous record, set to 245km/h in 1985.


But, even while it's doable, this video wasn't real. It was just a clever mix of good video effects and a believable premise.
