You don’t need to exhale when your initial breath was taken at the surface - this is a requirement when scuba diving as you are breathing compressed air.
And the bends is an accent speed thing, not a holding breath thing.
I would recommend to avoid taking your last breath at surface level, but instead take it 50 feet deep once you are completely submerged in water. The air is very wet down there, don’t be surprised.
This has been taught to me by a life-long observation of walleyes, who never make this stupid mistake.
Yeah previous reddit user here. Pretty OBVIOUS this is considering a breath is taken before exiting the vehicle at a depth of 50m.
This is simple high school physics. Let me use chatgpt to write some kindve algorithm to help grow my ego:
p(z) = 1 atm + (1.2 kg/m^3)(9.8 m/s^2)(-50 m)
Ill check back for my up votes and await my reddit gold.

Previous MySpace enjoyer here. Dimensional analysis for the second part of your right-hand sum would be in kg•m-3•m•s-2•m = kg•m-1•s-2 which is indeed a pressure, so this must be true, as my many years of not doing any serious physics anymore tend to prove.
You would need to exhale if the roof doesnt just implode and leak out all the air and you take a breath when the pressure between inside and outside of the car is equalized. You wouldn’t be able to open the door before water rising from the floor compresses air inside the car enough. Modern cars feel quite capable of keeping some air in them when the car sinks.
If car did hold it’s form, and no air exited and no water entered, the pressure would be surface-level pressure.
50 ft of water is about 22 psi or 1.5 bar. If you did breathe air that had equalized at 50 ft of water, there is a possibility of bends, but usually for dives that shallow, time duration is a big factor. So don’t sight-see.
It would be bad to not let any air escape your lungs during assent. But holding your breathe for the initial shock of all that water pressure crushing you is more important than some lingering idea in the back of your mind that holding your breathe too tight will get you a case of the bends.
I came to mention this is only a thing if you getting your air while underwater and was a bit sad to see someone already got to it and then a bit amused that the person argued it a bit.
Stupid tip.

Do walleyes go down to 50 feet?

LoL love the touch of using chatGPT to write their response for them.
The lamest way to barely participate in a conversation but still expect praise.

I miss myspace, with its music autoplaying and everything. But at least we still have each other
