Got a firsthand experience with this. I was dropping off my girlfriend and we stopped to talk in the car, with all the windows up. Over the course of the conversation we got more and more agitated at each other until I had a thought and pulled my Aranet out from my backpack. It was >3000ppm CO2. We opened windows and within 2 minutes all the agitation went away.
replyTo be fair, that might not just have been the CO2 dropping, but also the pattern interrupt + giving you both an easy and face-saving way out of that situation.
replyOr, you became aware of the agitation and interrupted it. The CO2 was a placebo. You have invested already in the idea, it all clicked in your mind.
replyI'm not sure this is a helpful comment. This is a common story with many medications, where someone notices their feelings are off and suddenly remembers that there is a probable root cause. It's why medications list side effects.
replyYour comment actually has me convinced that this isn't an issue. I've been a recirculation dude for my entire life, I literally don't drive any other way.
replyRelevant video of someone experimenting with a CO2 monitor in a car: https://youtu.be/hr9w-ZixAqc
replyBuildup of CO2 and reduction in O2 are two different effects. We're not in danger of running out of O2 in any everyday situation.
replyYeah, I measured over 5000ppm in a taxi with two passengers. Showed the driver how to enable air intake (he didn’t know about the feature) and tried to explain this is deadly. Pretty sure this is commonplace globally.
replyGenerally it’s a miracle to me so many people survive traffic on public roads, statistically.
Cars are not sufficiently sealed for that to make any kind of a difference.
replyTry it yourself. They really are

replyCars aren't hermetically sealed vessel. This is hilarious.
