"I wasn't injured," Norwood added. "Just scraped my arm."
Thousands of social media users, including celebrities such as Will Smith, have been posting footage of themselves dancing to the hit song.
While Norwood managed to escape with a few minor scrapes, police are the world and warning someone will be seriously injured or killed if people keep taking part in the challenge.
They say participants face fines for not wearing a seatbelt, driving without paying due attention, recording on a mobile while driving and endangering third parties.
An internet site started by a group of Spanish police officers is sharing a compilation video from officers in Boadilla, Madrid.
Cops there warn: "Teenagers should avoid carrying out '#inmyfeelingschallenge' in a vehicle. A vehicle is not a toy — use it with responsibility!"
The video shows several cases of young girls attempting to get out of the passenger seat while the car is still moving but falling on to the road.
In another clip, it appears that a woman driving a car moves over to the passenger seat in a bid to get out. One more shows a young male rapper so intent on dancing on the kerb that he collides with a lamp post.
He eventually makes a reappearance, tries to get back into the car but falls over in the road.
Police say it is just as dangerous for the driver who films the dance stunt as for the passenger who gets out of the car while it is still moving.
A spokesman said: "You should not drive without paying attention because you can endanger other people. Road safety is not a game."
Authorities in the US have tweeted a similar warning.
"Hopping out of a moving vehicle or jumping into lanes of traffic to show your dance moves is foolish and dangerous — to you and those around you," the National Transportation Safety Board said.
"There's a time and place for everything, but our nation's highways and roadways are no place for the #inmyfeelings challenge."
In Abu Dhabi, three social media stars were arrested after officials said their dancing "endangered lives, offended public morals and violated the traffic law".
