I know it's off topic but as far as the radio messages go, as an explenation for an issue or mechanical problem it's quite interesting but when, as was the case in the recent Alonso V Vettel battle and again with Rosberg V Hamilton, it just makes the drivers in question look like arseholes.
We slate Football players who have a go at the ref, and we can see that on the pitch and on camera. Why then do they feel the need to broadcast drivers, in the heat of the moment doing the same thing.
I think at this stage the words "casual fans" and "the show" would be wheeled out.
