Autonomous Vehicle
A vehicle that drives itself within a defined set of conditions, which is a different claim from driving itself.

When not to use it
- As a synonym for driver assistance. Levels 0 to 2 are a different product with different responsibility.
- To generalise a domain-specific safety result to driving in general, which the data cannot support.
- Where the operational design domain is undisclosed, in which case a safety figure has no interpretable scope.
Reach for something else instead
- Advanced driver assistance — the human drives and the system supports, appropriate where full automation is not achievable.
- Fixed-route automation — shuttles and rail on dedicated infrastructure, where the environment can be controlled directly.

Where people go wrong
- Reading a crash-rate comparison without checking how the human benchmark was constructed.
- Treating an operational design domain as a caveat rather than as the mechanism that makes performance achievable.
- Assuming domain expansion is linear in cost, which is the open question rather than a settled one.
