This unbelievable video shows a reckless cyclist leading police in a 60mph chase down the motorway.
Ignoring the blaring siren and pouring rain, the Czech rider tears down the busy road at great speed, before slipping past a white van.
But this rider is no Bradley Wiggins or Sir Chris Hoy, the rider is using a technique called 'drafting' - using the slipstream of a van in front to reduce the effects of drag.
It allows a vehicle to travel much faster than it would be able to otherwise.
The police car accelerates to 75mph to catch up, but undeterred, the cyclist moves behind a black van and repeats the same trick.
As they approach some roadworks, the brazen cyclist passes the van and then slows down to around 30mph.
But his daring fails this time and he is caught by the shouting police.
Any skilled cyclist would be capable of the trick, according to Gizmodo. The drafting world record is now 167mph, set by Dutch cyclist Fred Rompelberg in 1995.
He beat John Howard's previous record, which was set in 1985.
Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, car racing, and speedskating, although it is occasionally used in cross-country skiing, running and even swimming.
It is similar to when geese and some other birds fly in a V formation - allowing air movement from the front bird to circulate past those behind.
Some drivers have been known to draft behind other, larger vehicles, in an attempt to save fuel.
