I’ve read a few articles that though you breath in some pollution while biking, most of the exhaust is lower than you or nor concentrated enough to offset the good health aspects. Another thing to consider is that the inside of a car is actually quite filthy in terms of air quality as fumes accumulate inside the cabin. Here’s just one article discussing how cyclists breathe better air than drivers, even though we breathe at a much more rapid rate.

So you’re definitely healthier off biking.

“The point is–being almost killed regularly has made me an angry biker.” - best line EVAR

I bike down E street through downtown every day and then on other streets that don’t have bike lanes. I manage to not be too angry by expecting people to turn right in front of me, bike lane or no, and not using the bike lane on 9th St. Riding a little more aggressively than I might otherwise–by, say, passing up cars, getting into car lanes instead of bike lanes, and passing through intersections in a way that cars might not–helps avoid difficult situations. It’s a shame that cyclists are told by the law to wait at red lights; they’d often be safer passing through after a stop, but when they do that, drivers feel morally justified in taking their commuting/career/diminutive masculine member rage out of us more efficient travelers.
