Silverstone is under something of a cloud this weekend, both physically and metaphorically. Traffic problems have forced organisers to turn fans away, and thus the event is turning out to be a big disappointment for many. Nevertheless, assuming the weather doesn't get too bad, the show must go on. We have one hour of practice remaining for the drivers to work out what they're going to need to do well in qualifying. So far, Lotus and McLaren have been fast, with Kamui Kobayashi also showing well.
