Combined with the new tyres, future Merc development
may allow Lewis to have a serious crack at the WDC. However I'm not convinced they have opened up a clear performance advantage over Red Bull just yet. I reckon Hungary would have been a very different race with Vettel snapping at Hamiltons heels if he (Vettel) had not been held up by Button for so long. I guess Spa might tell us more.
If anyone is sure that Merc have opened up a clear advantage and Lewis has a very good chance at the WDC this year, they might feel the betting odds are pretty good right now (currently around 8/1 for Lewis vs 1/4 for Seb!).

The people doing the sport will decide it's fate not those who only comment. If SxSs and Extreme E buggies come to the fore than so be it, you can play tiddlywinks instead and yearn for yester year....
