After accusing Ferrari of cheating in Austin, Max Verstappen now wants to move on.
"It's a sensitive topic that I'm not going back to," Verstappen told Italy's Corriere della Sera newspaper.
"I prefer to look ahead. I'm only thinking of the race in Brazil."
The 22-year-old has also ruffled feathers recently with his aggressive driving.
When asked if he worries about losing the respect of his rivals, Verstappen said: "No one is a robot and everyone makes mistakes, especially when you're at the limit.
"Sometimes it's even good to make mistakes, for the lessons you take with you."
As for his recent outbursts, Verstappen admitted: "I'm probably too honest. And too direct."
However, he has plenty of fans, and many of them would like to see him charge for the 2020 title.
"I must be able to fight for the title," Verstappen insisted. "So far it hasn't happened because Mercedes has been miles and miles ahead of us.
"We will try again in 2020 but it is important for us to have a more powerful engine from Honda."
"Lewis will stop sooner or later, but it's more about the team than him," said Verstappen. "If Mercedes continues to dominate, it will be later rather than sooner."
