A data scientist in the automotive industry plays a crucial role in analyzing and interpreting complex digital data, such as the sensor data produced by cars, to assist in decision-making, improve business operations, and provide predictive insights. For instance, they can develop interactive charts to monitor the pressure in a car's tires over time. This can help to check if the tires are properly inflated when a car leaves the factory, how often customers reinflate them, and how long customers take to respond to a low-pressure alert. They can also find leak rates and do some predictive modeling on when tires are likely to go flat.

As an example, Berinato uses Tesla Motors' Data Scientist, Anmol Garg. Garg has used visual exploration to tap into the vast amount of sensor data Tesla cars produce. He developed an interactive chart that shows the pressure in a car's tires over time. "In true exploratory form, first created the visualizations and then found a variety of uses for them: to see whether tires are properly inflated when a car leaves the factory, how often customers reinflate them, and how long customers take to respond to a low-pressure alert; to find leak rates; and to do some predictive modeling on when tires are likely to go flat. The pressure of all four tires is visualized on a scatter plot, which, however inscrutable to a general audience, is clear to its intended audience," Berinato writes.
