>about half of what people spend on coffee each year: Yeah, but the difference there is that when people spend money on coffee, they're getting a cup of coffee out of the deal. When we spend money on traffic, we're getting hypertension and car accidents instead. That number is literally just time lost in traffic jams. That doesn't even factor in disutility incurred from actually being in traffic like lost sleep, road rage, traffic fatalities, etc.
