What kind of magic actually is supposed the shit in pic related do? I never bothered to find out but it started to grind my gears recently.

Air recirculation vs new air.

Is there any reason at all to use recirculation ever?

Keep warm air so the fans calm the fuck down

cooler AC

So I don't have to smell shit outside

If the air outside smells like shit, yes.

recycle ur farts

It heats the cabin up slightly quicker when it's cold but also circulates all the humid air in the cabin.

Your heater/AC works better if it isn't continually heating/cooling new air

That makes sense, thanks

Where do you drive that it smells so bad?

Ever driven by cow pastures?

Yes, it's not so bad that I have to close off the ventilation

This did not deserve its own thread anyway

>Where do you drive that it smells so bad?
On my way to work I drive past the sewage plant and it always smells like rancid fucking ass. Also, the poor neighborhoods near me all have septic systems so periodically I have to smell their shit on my way from my house.

>Is there any reason at all to use recirculation ever?
whenever the air outside the car is of much worse quality than inside
for example when driving through a long tunnel

>Is there any reason at all to use recirculation ever?
Many.
> Going past a sewage works, or freshly fertilised field
> Someone in front is smoking
> Smoke on the road
> Someone in front has a godawful engine problem
> Following a 2-stroke scooter
> AC kicks in faster

The smell of cows, silage, and cow shit isn't that bad. I like countryside smells.
Going past Staines, however? Shut the windows, recirculation on.

My car has a cabin filter, is the air still being filtered if its set to outside air?

>The smell of cows, silage, and cow shit isn't that bad. I like countryside smells.
I don't disagree, but I'm literally into bestiality and find the smell of a farm slightly arousing so you should probably get yourself checked, m8

there are almost always brainlets burning stuff right next to the roads where I live, the smell can sometimes linger for hours

>The smell of cows, silage, and cow shit isn't that bad. I like countryside smells.
POO

It only filters outside air anyway
Why would you need to filter air that was inside the car already?
