The cameras don't cover everything, and to be honest the most thrilling fights are not always in the front of the field - I know the focus for Jimmy too will be on the front runners, but with Jimmy's skills to get the lens pretty much joining in on the action he'll be able to cover things that the video doesn't.
And to be fair... The live stream is fun, but you know you'd much rather have the dust and debry flying around your face standing next to the track, enjoy the whistle of the motors and the constant symphony of electronic gizmos eminating from the pit area - all that while the sun is providing a warm, bright glow to enjoy - not to mention the nice atmosphere and comradery you usually have at these events
It'll be... challenging to recreate that spirit in a report if you're not actually there.
Of course though, the timing sheets and videos are a great piece of reference material to recap what happened.
