We've had one of three pre-season tests now, and there's just one more launch and one more race seat left to be filled/completed. All the pieces are starting to come together ahead of the 2013 season, and in honour of that, it's time for our infrequent Friday F1 questionnaire to make a return - your chance to take on five questions that ponder areas of the sport that have been hitting headlines of late. Ninety minutes and five questions later, we will all be much wiser, I think!
