Well, you do waste minutes of peoples lives. Let's see: 100 mio people driving 250 days/year, losing 10 min each way (so 20/day). That's about 12k lives of 80 years. It's actually worse, because you are wasting "awake time", so add 30%. It seems America isn't /that/ far of from the optimum. Maybe better driver education or better roads would be more effective?
