A man was spotted riding on the hood of a car barreling down the express lane of I-95 in Florida late Sunday — and appeared to be talking on the phone, according to one driver who recorded video of the wild stunt.

“What the actual f—k?” the driver said. “We are mid-highway.”

A female passenger in the car seemingly could not believe her eyes, according to the video.

“What is that?” she said. “Oh my God!”

The driver, Daniel Midah, told the Miami New Times that the man on the hood was somehow hanging onto the Mercedes-Benz C300 with one hand and appeared to be talking on the phone with his other hand. A woman behind the wheel, meanwhile, was also talking on the phone, likely to the man hanging onto her car on the “most dangerous highway” in the world, Midah surmised.

“It was literally crazy,” Midah, 19, told the newspaper. “The guy was looking left and right, a phone in one hand. It didn’t look like he was alarmed or fazed by anything. He was chilling, like nothing was weird.”

Midah called 911 after grabbing his phone to get footage of the surreal scene, he said.

“Obviously, like, it was funny, but it was also really dangerous,” he continued.

A 43-second video of the incident had been viewed more than 950,000 times as of Tuesday.

“Just to update some people asking, I have no idea what happened after, but I did call highway patrol and apparently it’s an ongoing investigation,” Midah tweeted Monday.

Joe Sanchez, a Florida Highway Patrol spokesman, confirmed to The Post that the agency is aware of the footage. Both the man on the hood and the driver will be cited for a moving violation if they are identified. The driver could also face reckless driving charges, he said.

“I can’t believe the guy is on the hood of that car, holding on for his dear life,” Sanchez said when asked what he thought upon seeing the footage. “It could’ve ended tragically.”
