More than 370,000 people were killed in car crashes in the U.S. from 2004 to 2013. Alcohol was involved in 31% of those, while distracted driving led to 18%, according to the Department of Transportation. Speeding was also a factor in almost a third of those deaths.

The Metrocosm blog recently brought those numbers to life in a graphic that, at first glance, looks more like a population density map or an electric grid glowing across the country.

But click on the interactive version and you’ll find an amazingly detailed and troubling look at what’s been happening on our roads over the past decade. Dots begin to take shape as men, women and children as you zoom in. The different colors represent drivers in red, passengers in orange, pedestrians in yellow, cyclists in blue and groups in purple.

For example, here’s a look at the Bay Bridge connecting San Francisco and Oakland. As you can see, one male pedestrian was killed by a car on the bridge over that time frame.

And here’s a look at midtown Manhattan, where driver distraction (illustrated by the green circles) is a serious danger. Pedestrians, understandably, appear to be more at risk in these parts.

Come 2050, an updated version of this map might look nothing like this one, according to a report from McKinsey & Company earlier in the year. The consulting firm’s analysis projects that, by the middle of the century, driverless cars could reduce deaths on the road by 90%.
