I don't think this has previously been suggested, but if it has I apologise.
But the amount of time's i've had to miss out on veiwing a race and missed out on point's (especially on my old account) due to weather etc is quite upsetting :(
I think they should develop an app for your phone's/tablet's etc. On it they could have live timing's, weather and the ability to make a un-scheduled stop on it. Also training and checking your design etc. It would be a great way to get into the racing on the move and be a easy mobile way to check out how your team's going on whilst your sat in a meeting for example :D
Again, I apologise if this has already been suggested, but it's just a way I think they can get people with little access to a laptop to engage a little bit more :-)
Let me know your thought's.
EDIT: App already in progress!
