Drivers retiring from F1 races is inevitable. Whether it's a smack against the barriers, colliding with a fellow competitor or suffering a mechanical failure, it's pretty common to see drivers stood at the side of the road mid way through the race - some more than others I might add.
However, not all GP retirements are as straightforward as crashing or breaking down. Over the years there have been some pretty strange reasons for drivers having to park their cars.
Here are six of the weirdest ways to retire from a Grand Prix:
RUNNING OVER A LOOSE DRAIN COVER
Juan Pablo Montoya's exit from the 2005 Chinese GP was caused by a dislodged drain cover. As you can see in the video, Montoya runs slightly wide which takes him straight over the piece of metal. His wheel was heavily damaged and this incident effectively handed the constructors championship to Renault that year.
STALLING WHILST WAVING TO THE CROWD (ON THE LAST LAP)
I'm sure everybody remembers this one. Having dominated the 1991 Canadian GP, Nigel Mansell decided to give his adoring fans a wave as he rounded the final lap of the race. Now, the official story from Williams and Mansell was that the car's gearbox failed as he came around the hairpin. Cynics however have suggested that his show boating meant he let the revs drop too low on his car and it stalled. I'll let you decide which one you believe...
CRASHING ON PURPOSE
Is this Formula 1's biggest scandal? Quite possibly. At the 2008 Singapore GP, Renault fixed the race by making their driver, Nelson Piquet Jr, crash his car just after Fernando Alonso had made a pitstop. This brought out the safety car and allowed Alonso to take the win.
GETTING STUCK IN THE PITLANE
Hamilton fans look away now. Lewis was agonisingly close to winning the world championship in his rookie season. However, he threw it away with this gaff whilst coming into the pit lane during the 2007 Chinese GP. On a drying track, McLaren left their driver out too long on severely worn intermediate tyres. When they finally brought Hamilton in, he had no grip and slid into the smallest gravel trap in history.
RUNNING OUT OF FUEL WHEN YOU DIDN'T NEED TO
It wasn't often that cars ran out of fuel during the era of pit stop refuelling - but Jean Alesi managed it. Despite being called in for a pit stop lap after lap at the Australian GP in 1997, Alesi carried on until, well, the inevitable happened.
COLLIDING WITH WILDLIFE
A stray marmot ruined Super Aguri driver, Anthony Davidson, chances of a great result at the 2007 Canadian GP. His bad luck was compounded when his team didn't even realise he was in the pits.
BEING TAKEN OUT BY YOUR TEAMMATE'S CAMERA
Before the days of Schumacher, a Ferrari 1-2 was a rare sight at Monza. The Italian GP in 1995 looked like it might change this with Alesi leading Berger. That was until Alesi's onboard camera fell off and bounced down the road to break Berger's left front.
