Driving costs in the US, per year:
- Carbon footprint: $20 billion
- Congestion: $78 billion
- "Accidents" (crashes): $220 billion
And even that wouldn't really work, because if there was no congestion, people would drive more and have more crashes. That's really the point of the article: America subsidizes driving, so people drive more than they would if they had to individually bear the cost of their driving. The result is that everybody pays.
