There was good news and bad news for the MotoGP paddock after the first day of practice at the Circuit of the Americas. The good news is that the work done to the track to try to remove the bumps had not made the track much more abrasive, as some had feared. Tires are wearing normally, so pit stops or worse will not be needed.
The bad news is that the work done to try to remove the bumps has not done anything to remove the bumps. It has moved them about a little, improved them in some places, made them worse in others, but the net effect has been zero, or worse than zero. What's worse, the process used has generated a huge amount of dust, bikes coming down the back straight billowing clouds of dust in their wake.
"It's worse than Qatar," Jack Miller said. "I said to the guys, 'I hope you've got the air filter in from Qatar, because you're going to need it'." At the first race of the season, the teams have to run a special air filter to prevent the desert dust from entering the engine and causing excessive wear. "The dust is far worse than Qatar, it's that crappy concrete dust," Miller explained.
