Ventilation in Cars?

Question

Most of the Cars are air proof & nearly sound proof also when all the doors & mirrors are completely closed.

That means, if a person driving the car by closing its all doors & mirrors, then he should die within 10~15 min. due to suffocation. Because there is no way for air to come in & go out from car.

But it doesn't happen !!! Many people drive (including me) by shutting all mirrors completely and putting on the A/C (on slow). But I never felt any suffocation !!! Or any difficulty in breathing !!

That mean there is some ventilation system in cars for sure who let the fresh air come in and keep refreshing the inner atmosphere.

Anyone knows how this system works ?

Answer 1

the process of suffocation starts when you are inside the car with AC switched off, fresh air intake vents are shut and all windows closed.

its dangerous to take a nap in the car and also dont keep your pets and kids in such a condition without ventilation.

the car engine can stop suddenly during your nap cutting off fresh air intake to the cabin leading to suffocation and death.
