A Knowledge of autonomous vehicles accumulated unevenly across public roads with mixed users. A striking report could establish that a pattern existed, yet it could not show whether sensor fusion operated elsewhere. Researchers examining autonomous vehicles therefore moved toward shared definitions and planned comparisons based on scenario testing rather than discarding the earlier record. B For the present account of autonomous vehicles, automated driving systems combine sensors, maps and software to perform some or all driving tasks under defined conditions. In transport engineering, the term operational design domain refers to the specific conditions in which an automated system is designed to work. The definition gives researchers a common starting point for discussing autonomous vehicles, but it does not identify a cause by itself. Two observations of autonomous vehicles can share the label operational design domain while differing in scale, timing or origin. C The evidence about autonomous vehicles is informative but conditional. One point relevant to autonomous vehicles is that automation performs well in constrained settings, but unusual road layouts, weather and human behaviour remain difficult. Researchers test sensor fusion as an explanation. Evidence reviewed for autonomous vehicles shows that software combines cameras, radar, lidar and motion data to estimate objects and road conditions. Confidence in sensor fusion rises when independent measures of autonomous vehicles agree and rival explanations fail, rather than when a single comparison happens to be statistically precise. D Researchers rely chiefly on scenario testing to investigate autonomous vehicles. Research on autonomous vehicles has found that developers combine closed tracks, simulation and supervised road data to test rare and ordinary situations. They decide their comparison, exclusions and outcome measures for autonomous vehicles in advance. A result about autonomous vehicles is treated as stronger when it survives more than one source of evidence, not simply when one instrument measuring autonomous vehicles reports many decimal places. E Practical programmes translate evidence about autonomous vehicles into action. The discussion of autonomous vehicles notes that regulators require clear operating limits, incident reporting and safe transfer or fallback behaviour. Their stated focus is safer mobility. Teams working on autonomous vehicles compare later outcomes with conditions before implementation and record unintended effects. This evaluation of autonomous vehicles determines whether the original explanation involving sensor fusion remains useful outside the research setting. F Interpretation of autonomous vehicles must stop short of a universal claim. For the present account of autonomous vehicles, kilometres driven are not a complete safety measure if easy and difficult conditions differ between systems. Future work on autonomous vehicles is organised around shared safety cases. For future research on autonomous vehicles, shared safety cases will connect test scenarios, system limits and evidence for real-world risk. This use of shared safety cases targets a specific uncertainty about autonomous vehicles rather than merely increasing the volume of data.
