Max Verstappen has joked that Red Bull might be better off communicating in sign language after issues on the team radio continued in Austin.
The Dutchman finished the United States Grand Prix in third after he was passed by Ferrari's Charles Leclerc in the closing stages.
Verstappen has suffered in the technical department before and Sunday's race was another "disaster" when trying to communicate with the pit wall.
"It's not the second time," he told media in the news conference. "It's already, I don't know how many times this year.
"Maybe we should just start communicating in sign language. It's probably cheaper as well. It's a disaster. Yeah, it's a disaster. It's really frustrating, to be honest."
His teammate Isack Hadjar, who finished in sixth, was also struggling to communicate with the team, but luckily for Hadjar it was only the first time it's happened.

"Honestly, for me it's the first time it's happening the whole year and I can tell you it's not nice," he said. "I can't hear anything."
When asked how the team communicate with him, he replied: "I don't know, I just hear some kind of box, box and then I box. I almost pitted at the wrong time once."
Verstappen's radio has been riddled with issues throughout the season, but notably in Singapore when his race engineer Gianpiero Lambiase improvised using silent code when deciding which strategy to take.
He still went on to take back-to-back victories at the Bahrain Grand Prix in Malaysia and Singapore before heading to the U.S.
