I don't think anyone is really surprised Lotus confirmed Romain Grosjean for 2013, no doubt he has the speed, he was robbed of a GP win in 2012 in Valencia and has been a quick qualifier. I'm sure Lotus got a great deal on him considering the "annus horribilis" he had in 2012.
The official announcement cane right after Grosjean won the Race of Champions in Bangkok this past week end, defeating Tom Kristensen in the final.
It was....rough. Despite incessant twitter updates from @Drive, it was not shown live so results were known nine hours before the "broadcast". When time came to watch the festivities, many people just got a big fat "please stand by" sign on YouTube.
I tried for about a half hour and just gave up. You can see segments of the race now on Drive today though I'm not sure why they chose not just stream the live commentary from the Radio Lemans crew.
Maybe next year.
Earlier in the competition, ironically it was Vettel who crashed out...
