Jenson Button hit out an at 'idiotic' move from Kamui Kobayashi after being forced to retire from the Korean Grand Prix on the opening lap.
Button sustained front-right suspension damage when he was collected by the Sauber man going into turn three, with the incident also seeing the Mercedes of Nico Rosberg forced into retirement.
The clash - which Button referred to as 'idiotic' on his team radio immediately afterwards - came after Button had been forced to take evasive action at turn one when Sergio Perez out-braked himself at the start.
It left Button watching on from the sidelines and the Briton was critical of the driving that had seen him put into retirement.
"I got a really good start, got past Michael and alongside Nico into turn one," Button told Sky Sports F1
. "Then 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.
"Then going down the back-straight, I was having a good little drag race with Nico Rosberg and suddenly I felt a big bang on the right hand side and had 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."
Kobayashi was handed a drive-through for the incident although Button said he didn't feel the punishment had fitted the crime.
"I don't think so,” he said. “You wipe out two cars that have a very good chance of scoring points…”
Kobayashi was later forced to retire from the race, amidst on-going speculation that he could lose his drive with Sauber
despite his podium finish a week earlier in Japan.
