JEREZ, Spain - After Jenson Button stunned his rivals with the pace of the new McLaren, Lotus' Romain Grosjean was even quicker at the second day of testing in Jerez, Spain.Lotus' Romain Grosjean, after a nightmare 2012 season, wants to be consistent and (more important) lose his first-lap jitters during the 2013 F1 season.Grosjean, banned at Monza in 2012 and written off as a "first-lap nutcase" by Mark Webber, insists he is not getting carried away with the tantalising potential of the new black E21.Gosjean said: "The world title is not my goal. In 2013, I particularly want to be consistent. I know that the speed is there, in me. But in some situations I have to be more patient."Speed isn't the issue here Romain, losing your first lap jitters however should be your top priority.
