Let this be sex videosa lesson to us all.

A man riding a scooter was going down a street in the Chinese city of Guangxi, when a massive sinkhole suddenly opened up ahead of him.

His arm up, looking at his cell phone, he remains oblivious to the scene and carries on driving -- until he falls right in.

Here's the moment it happened:

According to Chinese reports, the man was uninjured and managed to climb out of the pit, which measured two metres (6 ft) deep, eight metres long (26 ft) and five meters (16 ft) wide.

While sinkholes don't usually open in the middle of the road for no reason, it's been happening more in rapidly urbanising parts of China, where extensive roadworks shifts the soil underneath the asphalt.

Authorities have yet to offer an official reason for the sinkhole.

But users on Chinese social media website Weibo had little sympathy for the rider.

"He's using a phone while riding a scooter. Sorry I really have no sympathy," said one user.

"It's fine if you walk on the sidewalk while using your phone but this is too much, it's so dangerous," another chipped in.

"What the heck was he thinking playing with his phone while riding?" one asked.

Well one thing's for sure, he probably won't be using his phone while driving again for a long time.
