Horrifying footage released by an Australian fire service shows why you should never sit in the passenger seat of a car with your feet on the dashboard.
This might seem obvious, but if you have a crash it'll be bad. Like, really bad.
The video was shared by the Narrabeen Fire and Rescue Service - it shows a passenger side airbag being set off while the car isn't moving.
Basically, when the airbag goes off it does so with such force that it completely wrecks the car's front windshield.
Now imagine if you were sat lazily resting your feet on the dashboard of that particular car. We can all see how that might end up, can't we?
This particular Aussie fire service, based in the Northern Beaches area of capital city Sydney, shared the vid on its Facebook page with the intention of raising awareness. It'll certainly do that.
The fire brigade said: "A friendly reminder to keep your feet off the dashboard when travelling in vehicles."
The Australian National Roads and Motorists Association (NRMA) reported that in 2016, more than 400 people were admitted to hospital with injuries related to putting feet on the dashboard of a car.
Not only can your feet get pushed back into your own face, which sounds bad enough, the seatbelt can also cause a whole load of damage.
Because the body gets pushed down underneath the belt, some internal organs can bear the true force of the impact.
Dr John Crozier, from the Royal Australasian College of Surgeons, told the NRMA that potential injuries include things like 'a ruptured bowel' and 'a torn aorta'. Oh, and 'the spinal column itself can be torn apart'.
He then added - fairly obviously - that "injuries like that will paralyse and they may well kill."
This latest warning comes after a woman broke all the bones in her face after a crash while her feet were up on the dash.
Grainne Kelly, who was 22 at the time of the accident, had to have her forehead removed after her boyfriend's Range Rover crashed, causing an airbag underneath her feet to detonate.
She said: "I had nothing in place of my forehead. My head sunk in and I looked a little strange.
"I had decided along the way that I would be more comfortable if my feet were on the dashboard.
"By doing this my feet were placed directly on top of the airbag without realising.
"When the Jeep collided with the wall, the airbags inflated as they do but because my feet were on top of mine it actually pushed my feet, knees-first, into my face."
Kelly - now 35 years old - then urged people not to follow the actions of celebrities such as Kim Kardashian and Selena Gomez, who have been pictured in the dangerous position.
She continued: "[These] people... do not realise that they are sending out the WRONG message by putting their feet on the dashboard.
"If only they knew how dangerous it is.
"To say this breaks my heart would be an understatement. I feel helpless looking at these photos."Featured Image Credit: Facebook/Narrabeen Fire and Rescue
