The race weekend was subjected to variable weather with cool, rainy periods giving way to warm and sunny weather on Sunday. The peak track temperature of 40°C during was the warmest reading for the whole weekend.
Q&A with Shinji Aoki – Manager, Bridgestone Motorsport Tyre Development Department
On Friday the MotoGP riders had their first ever wet session at Circuit of the Americas. What can you tell us about the grip level of the circuit in the wet, and how your wet tyres performed?

122 seconds in the life of Marc Márquez
There was quite an admission of guilt from the podium trio at Austin on Sunday. Not one of the top three – Marc Márquez, Andrea Dovizioso or Valentino Rossi – had ridden the entire race flat-out. They’re not getting lazy or anything, they just knew that Austin’s 20 corners and especially the Turn 3/4/5/6/7/8/9 flip-flops and the never-ending Turn 16/17/18 right-hander chew the hell out of the front tyre. So don’t abuse it or it will abuse you.
All these things considered, Márquez was miraculous on race day. Following overnight rain, the track had lost some grip, so he held back in the early laps while Dovizioso crept ahead at the rate of several tenths a lap. Was Márquez struggling? Was he, hell. He was just getting acquainted with the new grip character and once he knew what he was dealing with, he surged forward and that was that. Another brilliant win, his 20th in the premier class, which puts him equal with his forefather Freddie Spencer.
But I won’t remember the weekend for Sunday’s 43-minute race. Much more memorable was what happened on Saturday afternoon.
Keep Austin Weird is the slogan of the Austin Independent Business Alliance, meant to promote small businesses in the Texan city. The Circuit of the Americas certainly did its bit this weekend. We had a delay due to marshals and medical support staff not being at their posts. We had a red flag due to a stray dog on the track. We had delays due to fog, we had one day of rain, followed by two days of peering at the skies wondering when the massive rainstorms which had been forecast would arrive. They never did. We had Keanu Reeves, star of both The Matrix and Bill And Ted's Excellent Adventure, in the paddock, as well Carol Vorderman, British TV's brainiest beauty, at least for gentlemen of a certain age. You wouldn't imagine it could get much weirder.
It did get weirder, though. The MotoGP race ended up delayed by half an hour, because rainwater was dripping off a bridge over the track around Turn 3, leaving a puddle of standing water on the circuit. There had been some water there during the Moto2 race, Sam Lowes saying he had been very cautious through that section, as the bike was moving about. Franco Morbidelli had reveled in it, enjoying the feeling of the rear moving around as he powered through the puddle. Racers will be racers.
The sun which emerged at the start of the MotoGP race made the situation worse, paradoxically. Elsewhere, the track was fully dry and warm, but standing water remained in the shadow of the bridge. While making its final inspection lap of the track five minutes before the start, the safety car reported the water to Race Direction, and Race Director Mike Webb pushed the big red button to delay the start. That is not an easy decision. Webb knows that as soon as he presses the button to delay the start of a MotoGP race, it costs Dorna millions of dollars in TV penalty clauses around the world. It does not stop him pressing it, however, safety being paramount. If anyone ever wondered if Dorna sacrificed safety for TV money, their question was answered on Sunday.
