Verstappen tests Hamilton's brakes during FP2

Max Verstappen was very frustrated during the second free practice of the United States Grand Prix. The Dutchman was not happy with the traffic, but also complained about the actions of Lewis Hamilton.

Both men were getting ready to start their fast lap, but it didn't go smoothly. The race isn't until Sunday, but the rivals couldn't resist racing during the practice session. An earlier video shows Hamilton and Verstappen entering the straight side by side and the Dutchman being pushed off the track. "Stupid idiot" was Verstappen's response over the radio.

A more extensive video shows what exactly preceded the incident between the competitors. It shows Verstappen overtaking Hamilton and then slamming on the brakes, forcing Hamilton to hit the brakes as well.
