Jenson Button decisively won the 2012 Grand Prix of Belgium, lights to flag, after first lap carnage through La Source shunted Lewis Hamilton, Fernando Alonso, Roman Grosjean and Sergio Perez out of the race. Stewards later (stupidly) penalized Grosjean with a one-race ban and a €50,000 fine. Grosjean Ridiculously Suspended, Maldonado Slapped on the Wrist Again | Bleacher Report.

The full statement from the Stewards said they

“regard this as an extremely serious breach of the regulations which had the potential to cause injury to others. It eliminated leading championship contenders from the race. The stewards note the team conceded the action of the driver was an extremely serious mistake and an error of judgement. Neither the team nor the driver made any submission in mitigation of penalty.” For his part, Grosjean conceded “I did a mistake and I misjudged the gap with Lewis. I was sure I was in front of him. So a small mistake made a big incident. I didn’t change my line, I went from left to right. I was not really wanting to put anyone in the wall. I’m not here to stop the race in the first corner. I’m very, very sorry and I’m glad that nobody is hurt. But I have to say it is a very, very hard decision to hear.”
