Without commentary or live timing I don't know whether it would be all that interesting. Maybe it would, I don't know. I think I'm going to rely on stills of the new cars until Melbourne...and obviously watch the testing times religiously!
Up until recently, the Circuit Catalunya actually provided a live timing feed of testing events... I really hope they come back to it again this year - it was an automated system, much like the one used for F1. However, I suspect either the teams weren't happy, or it proved too expensive to run. Either way, if they return this then it will be a very bright day!
