Idle with AC: 700 rpm
diff: 150 rpm
freeway: 3000 rpm
550 rpm / 60 sec/min = 9 rps.
9 RPS (measured) X 2.5L (nom total cylinder cap) X 0.25 (Otto four-stroke) = 5.6 L/sec
I personally breathe maybe a tenth of that? Or less?
I once freaked on a concrete-lined freeway into LA when I realized all these creeping cars were competing with me for oxygen.
