Sorry but I just dont see that at all and I hate to tell you this but Massa DID destroy Jensons race completely. If neither had Kers the effect would have been exactly the same lol. Jenson was massively faster than Massa in terms of outright pace in the corners (the only way you stand a chance of sticking to the guy in front of you when that close) and yet, despite the fact he could use the DRS on the pit straight where it should count (admittedly a poor choice by the regulators but..) as well as Kers he just couldnt get past him through a straight line advantage. The only place he stood a chance was at the point in the track that was likely to send him off which was only acheived by getting a sustained tow and not through full on Kers usage anyway. This was backed up by the fact that Alonso pulled them both in with absolutely no problem pointing to Massa slowing them both down significantly which, seemingly by your logic, should make him easy prey. Kers vs Kers = stalemate which leaves you back in the same position as neither car having it. Its a waste of time, money, resources and bloody criminal the way they let them use batteries. Add in red bulls not using it at all and the case is more than made for me lol. The DRS seemed to help some people (though by no means lots of people) but Kers is no advantage to anyone when they all have it.
