Every Subway rider has a few irrational fears while they're riding through the city. Whether it's falling in the train tracks, walking from cart to cart or in this case a Subway door swinging WIDE open mid Subway ride.
While the train that the person is riding is unknown, someone caught this terrifying video of one of the cart doors swinging wide open while the train was moving from station to station.
They really mean it when they say don't lean on the doors.
Check out the video below.
