Jenson Button lamented the loss of teams' points in Korea after being taken out on the first lap by Kamui Kobayashi.
Fighting for track position at the start at the Yeongam circuit, Button moved up from his 11th place on the grid to challenge the Mercedes drivers for position.
However, instead of making up ground the Brit found himself punted out of the grand prix as first Sergio Perez hit him and then Kobayashi came flying down the inside of Turn Three, smashing into the Brit's McLaren.
"It's as if the race is two corners long," Button told the BBC. "I don't know what's going on but it's pretty disappointing.
"It's a long race and there are so many overtaking opportunities here so there's no need to do that."
Explaining what he believes happened, Button revealed that he was hit by not one but both Sauber drivers.
"Perez came from nowhere, dived up the inside and hit the car in front. So I had to move out of the way - it was too late really to make that move as it proved when he hit the car in front.
"And then going down the back-straight, I was having a good little drag race with Nico Rosberg, then suddenly I felt a big bang on the right hand side and Kamui flying past. It is pretty poor driving standards considering this is the pinnacle of motorsport and it is such a long race.
"These guys are going round having fun out there and fighting for points - the race is not two corners long and some people need to learn that and whether they will ever learn that we will see."
The retirement, Button says, has "definitely" put an end to any chance he had of fighting for the Drivers' title while also costing McLaren in the Constructors' race.
"No, definitely not," he said when asked if he still had a shot at the Drivers' title.
"I'm going to enjoy myself over the next few races."
He added: "Points for the team would have been really important, but it's out of our hands."
