I've been thinking about the notion - continually used by f1 journalists/teams to explain why refuelling should not return - which essentially boils down to:
'more overtakes equals better racing'
Bhall has been very detailed about why refuelling is not the inherent cause of lack of overtakes, but we should also recognise that the above is not a hard and fast rule.
I'm always rewatching (over and over again!) old races and two I recently rewatched are good illustrations of this:
2013 Spanish gp
2005 San Marino gp
I should start by saying that I think 2013 Spain is a reasonably entertaining race, particularly in the first two stints; but it was also littered with overtakes, none of which I think were of massive entertainment value - other than alonso off the start which is irrelevant to the conversation.
It also featured the sky commentators - inc the same Martin brundle who recently rejected the idea of refuelling for fear it would mean less on track overtakes - bemoaning the fact that drivers were not pushing the tyres or defending hard.
2005 San Marino on the other hand had, as I recall, only one on track overtake of note - Schumacher on Button, which owed something to back markers. Rather, it is a race remembered and lauded primarily *because* of the lack of a race lead affecting overtake. Yes, if the overtake had been successful it would have changed the story - arguably to a better one - but only if the overtake was very difficult and the exception rather than the norm.
Now, of course the circumstances that contrived to make the 2005 race so interesting are another conversation, but we should acknowledge that sheer volume of overtakes should not be f1's goal - you could in fact argue quite the opposite.
