According to analysis by the Texas A&M Transportation Institute, the average American commuter spends 42 hours per year stuck in rush-hour traffic. In the Los Angeles area, the figure is nearly twice that, equivalent to more than three days.

The total cost of traffic associated with lost time and wasted fuel exceeds $100 billion per year. As time slips away, idling vehicles add pollution, which has environmental and health consequences, including contributions to climate change. Long-term exposure to vehicle exhaust is associated with respiratory problems, especially in children.
