Tracking Longitudinal Changes in Awareness, Usage, and Trust in Autonomous Vehicles: Evidence from Large-Scale, Nationally Representative U.S. Surveys (2023-2025).
Article in Transport policy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Tracking attitudes toward autonomous vehicles (AVs) is crucial to understand the facilitators and barriers to the further integration of AVs into society. Despite rapid progress in AV deployment across several U.S. metropolitan areas, high-quality surveys, particularly longitudinal data, are lacking to track the secular trend in public trust and experience with AV technology. The current study draws on three waves of survey data from a nationally representative longitudinal panel, between 2023 and 2025, to examine trends in awareness, usage, and trust in AVs, and to assess in what ways exposure to AVs might shape public trust. Results from chi-squared and two-sample proportion tests suggested a gradual increase in AV awareness and use. A difference-in-differences (DiD) analysis further revealed that individuals who had previously used AVs, despite being a small group, exhibited significantly higher trust after exposure. Additionally, persistent demographic differences were observed in awareness, usage, and trust in AV technology. Younger, higher-income, and more educated individuals reported greater awareness and trust, whereas older adults and lower-income groups remained hesitant. Women expressed lower levels of trust and more uncertainty than men. While overall adoption remains limited, the findings imply that direct interaction with AVs, not just an increase in awareness, may be a key driver in building trust. Demonstration initiatives, in combination with public education, could be critical for deeper integration of AVs into day-to-day life. As deployment continues to accelerate, continued efforts to monitor the change in demographic disparities will be essential to ensure equitable access to AV technology.
