Motorcyclist grabs feet hanging out of vehicle window on freeway

A new video that demonstrates why you shouldn't stick your feet out of the window of a car while traveling on the freeway is going viral.

San Diego-based YouTuber Zim Killgore posted a video on Sunday showing him passing a car with a person's feet dangling out of the back window and grabbing one.

The person retracts their feet into the vehicle quickly as Killgore speeds off, and the experience probably left them with a new lesson learned.

The video has been viewed more than 530,000 times since it was posted.
