USA smartphone adoption, pedestrian fatalities, and the average weight SUVs/pickups
* **National Highway Traffic Safety Administration (NHTSA):** The historical pedestrian fatality statistics are sourced directly from the NHTSA’s Fatality Analysis Reporting System (FARS), which tracks traffic fatalities nationwide. https://www.nhtsa.gov/book/countermeasures-that-work/pedestrian-safety
* **Environmental Protection Agency (EPA):** The historical vehicle weight data and the market shift toward light trucks and SUVs come from the EPA’s annual Automotive Trends Report, which maintains data on every new light-duty vehicle produced since 1975. https://www.epa.gov/automotive-trends/highlights-automotive-trends-report
* **Pew Research Center:** The timeline of smartphone adoption and mobile internet use in the United States is tracked by the Pew Research Center’s National Public Opinion Reference Surveys. https://www.pewresearch.org/short-reads/2026/01/08/internet-use-smartphone-ownership-digital-divides-in-u-s/
* **Insurance Institute for Highway Safety (IIHS):** The safety analysis regarding vehicle lethality, front-end geometry (the “leading edge”), and blind spots during pedestrian impacts relies on multiple IIHS studies, including their specific analyses of pedestrian crash lethality by vehicle type. https://www.iihs.org/research-areas/fatality-statistics/detail/pedestrians
