A video recorded in Yellowstone National Park shows the shocking moment humans have feared for years when a bear effortlessly opens the door of a car. Next time you go to bed and think you’re OK leaving the door unlocked, bear that in mind.
A family stopped to take pictures of the black bear on a drive through the park which occupies parts of Wyoming, Montana, and Idaho.

Luckily the photographer does not flinch and quickly closes the door.
But the threshold has been crossed - animals now know how to get into our safety zones.
The screams of those in the back of the car mark the horror mankind now knows.
