Yawn! there is really nothing to warrant all that analysis
When the team behind you pits you have to hold your cables in so they can leave. The brawn mechanics were letting the force india driver leave
Kovi stopped as soon as he knew there was problems, just happened to be in front of the brawns. With fuel and fire behind you it would be daft to do anything other than stop immediately and off line
The Brawn chaps kindly helped kovi out and thus cleared their pit box
The fines are proportional to how much you affect the other driver. Slowing them down to avoid contact - small, setting them on fire - big!
