You don't pay attention to either the race or what the riders say do you. Marquez says he pushed because he felt good, confident. He didn't think he was taking too much risk at that point. The front tyre wasn't yelling "WARNING CRASH COMING" as you happily point out it was saying to Pedrosa from your armchair. So what are you saying, they should take heed of the early warning signs and slow down like Lorenzo at Assen? At least salvage a point? Boy you are one confused poster.
Then you think Marquez was riding around thinking about big bad Vinales rather than just riding the RCV. He in his head. Yeah sure like Kesh says its the same rubbish we had to put up with all through 2008. The championship is influenced far more by Michelin than it is by any rider in ones 'head'. I predict here and now every championship contender is going to suffer a front end loss and crash in at least one race. Why do I predict this? Well, Michelin front tires are ..... Have you been paying attention. Count the front crashes simply going back to Qatar. Zarco, Crutchlow, Ianonne, Marquez, Pedrosa, Espargaro, Petrucci off the top of my head.
Rossi clearly has a strategy this year. He didn't push at all during testing. He sits way back in every practice. He's had a moan about the tires. Imo, he's obviously sandbagging, and in fact he's really only a tire change away from being the favorite for the championship. But he doesn't want the pressure of favorite status. He's happy to leave that pressure on Marquez and Vinales. Just like any good poker player he's not showing his hand early and I predict he will continue this pattern of appearing lost all week during practice then suddenly coming good on race day to take a safe 2nd or 3rd, and if both happen to crash, he will take the odd win.
I would say if there's one rider who may make it through the season without crashing the dodgy front its Rossi. All up its a very smart strategy. Well see if it pays off but imo it already has. Next the pressure will slowly go on to, yes you guessed it, Vinales.
