Would the BBC show the practise sessions on their website?
I think the drive to show things like the practice sessions and race build up is as much from F1 itself as it is from the broadcaster, so I expect the BBC will continue to do it. It the BBC drop any of the features ITV have (practice on website, live qualifying, live and rerun race, race build up, build up feature items, etc) then they will get slaughtered
thinking about it, minus the adverts, ITV coverage isnt that bad really....
