Formula 1 drivers are passionate people. Tensions run high in the cockpit, and when things go wrong, many of them find it hard to hide their displeasure.
When a driver has made a mistake by himself, they make it known that it was their own fault. When another competitor is involved, that's when things get interesting.
After Max Verstappen and Esteban Ocon's off-track run in at the Brazilian GP, I began thinking about the other times when F1 drivers have had an incident, and - in the heat of the moment - have let their emotions spill over.
Here are five of the best F1 driver bust-ups:
MICHAEL SCHUMACHER VS DAVID COULTHARD: SPA 1998
Everyone remembers this one, right? Schumacher was leading the soaking wet race, and was coming up to lap Coulthard's McLaren. DC backed off, and in the terrible conditions Schumacher was unsighted, ploughing into the McLaren's rear end. Michael was pretty unhappy about it, and made made his way to DC's garage to show his displeasure.
NELSON PIQUET VS ELISEO SALAZAR: HOCKENHEIM 1982
With a 26 second lead, Piquet came up to lap Eliseo Salazar. Rather than file in behind, Salazar remained alongside the Brazilian's Brabham as they entered the chicane, nudging the latter off the track and out of the race. The rest is history.
AYRTON SENNA VS EDDIE IRVINE: SUZUKA 1993
Despite winning the race, Senna was outraged after rookie driver, Eddie Irvine, unlapped himself. There was no contact between the two drivers, but Senna was incensed, and paid Irvine a visit after the race. The Irishman received a few choice words from Ayrton, and was also given a knuckle sandwich too.
JARNO TRULLI VS ADRIAN SUTIL: INTERLAGOS 2009
This pair collided on lap 1 of the 2009 Brazilian GP, wiping them both out of the race. Trulli felt it was Sutil's fault. Sutil felt it was Trulli's fault. The argument rumbled on to the next race, where the two drivers exchanged a words in the pre-race press conference. The whole thing is worth it just for Alonso and Raikkonen's reactions.
NIGEL MANSELL VS AYRTON SENNA: SPA 1987
Senna and Mansell clashed after battling for the lead of the 1987 Belgium GP. After the incident, Mansell stormed down the pitlane and pinned Senna up against the wall in a fiery clash in the Lotus garage.
