We used to get PIP (Picture in Picture) of the pitstops whilst the main shot was of the cars coming down the pit straight. It always worked well in the past, I don’t know why they don’t do it nowadays. :S
With regards the split screen, I like what the BBC are doing for the Quali lap analysis between 1st and 2nd, more of that please as it really gives a good idea of where one driver was faster than the on their respective laps, but during the race? I think it would confuse the directors even more than they seem to be now.
I’d like on board PIP as an option when following a close battle but other than that I am pretty happy with the camera views we get, it is just the director that organises them who should, on occasion, be shot.
