SAO PAULO, Brazil - Romain Grosjean’s future is still unclear as Lotus make the French driver wait for an announcement.The team says it values the young driver's raw speed but he's had a less-than-impressive 2012 season.Team boss Eric Boullier said: "We're having a few days or a few weeks of consideration. This season, there were not terrible things and not great things, but we're not going to bury the kid, he did three podiums."SPEED OR CONSISTENCY?Team owner Genii's Gerard Lopez said: "The chance that he races with us in 2013 is great."Grosjean, 26, admitted in Brazil that he was exhausted after the ups and downs of his return to F1 in 2012. "It is time to stop and take two months off. I hope I'll be there in 2013."While he takes a break the team will be considering whether his speed trumps his lack of consistency. Lopez again: "Romain is one of the fastest drivers in F1. He understands the car, he can get the most from it, but he hasn't done everything we asked of him, especially in terms of consistency. then, the kind of speed he has does not grow on trees."He's not yet confirmed for 2013 because we've not had time to sit down and discuss it together with the engineers. My desire is to see Romain in the car, but it depends more on him than me."
