Correct me if I’m wrong, but you can avoid most (all minus epsilon) of the exhaust fumes be keeping your windows closed and recirculating air from the vents. Commuters should be more concerned with having a car accident. AFAIK, people discount the relatively high risk of death and serious injury resulting from traffic accidents.
I find that if I keep the vents closed on for long enough, then I start to feel somewhat sleepy and don’t notice it. This is a bad thing to happen while driving.
I suspect that it may be caused by consuming oxygen faster than the imperfectly sealed vents are letting more oxygen in; the symptoms vanish quickly if I restore access to external air, either by opening the vents or opening the window.

Interesting. I’m going to try to look out for that from here on.
