The thing is Lorenzo has some blame in that he did try to get back on the racing line very fast. I think he did it to stop Dovi from getting back in front of him as this is a corner that has a bit of run off and allows for the rider to maintain some speed. I'm sure he was aware of Pedrosa behind them, just how far back Pedrosa was is something he couldn't calculate. I don't think he expected Pedrosa to be there.
And with that said, I still maintain the incident wouldn't have happened without Dovi involved.
It's a good 90/10 here. 90% Dovi and 10% Lorenzo. Still no way Pedrosa should take any blame. Only way he can say he could have avoided the accident, is to not get out of bed and go racing that day.
