Between 2013 and 2023, road passenger transport movements by passenger cars in the US remained relatively steady with minor fluctuations, except for a significant drop in 2020 attributable to the COVID-19 pandemic. In 2023, the movement stood at 6.254 trillion passenger kilometers, an increase of 4.27% from the previous year. The overall CAGR for the period from 2018 to 2023 was 0.83%, suggesting modest growth interrupted by the pandemic.

Future projections indicate consistent growth in road passenger transport by passenger cars, with a forecast CAGR of 0.95% from 2024 to 2028. This demonstrates a stable but slightly accelerating trend in passenger movements, reaching 6.6372 trillion passenger kilometers by 2028.

Future trends to watch for:

Impact of emerging technologies such as autonomous vehicles on travel patterns.
Influence of environmental policies on passenger car usage.
Potential shifts in mobility preferences due to urbanization and changing societal trends.
Economic factors, including fuel prices and economic growth, impacting passenger transport volumes.
