AI exposure: Subway and Streetcar Operators
Operate subway or elevated suburban trains with no separate locomotive, or electric-powered streetcar, to transport passengers. May handle fares.
Reading this score
computedSubway and Streetcar Operators is one of the unusual cases where capability and friction are both high. Current systems can produce a great deal of this work, with average capability across its tasks at 2.2 out of 4. Only 33.4% of the weighted task load comes out as exposed, because 22.1% of it runs into something structural. Jobs in this band tend not to disappear. They change shape, and the person stays.
What holds the line here is embodiment. Across this occupation's 10 tasks it averages 1.73 out of 3, the highest of the five friction dimensions. In plain terms, the work has to happen in physical space. A language model cannot move matter. Until the robotics to do this work is both good enough and cheap enough to deploy widely, capability in software does not reach it.
The most exposed thing this job does is Make announcements to passengers, at 80.0%. The least is Direct emergency evacuation procedures, at 3.3%. A gap of 76.7% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.
Within transportation and material moving occupations, this one is more exposed than most. The median across the 52 roles in the group is 24.2%, and only 8 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.
What would move this score. Of 10 tasks, 4 are currently banded exposed, 1 assisted and 5 untouched. For that distribution to shift materially would take cheaper ways to verify output, since the cost of checking is currently doing more to hold this work in place than the cost of producing it. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.
Where the score comes from
judgedEvery task is scored through the standardised work activities it maps to. These are this occupation’s averages on the six rubric dimensions. Capability is what AI can do; the other five are what stands in the way.
| Dimension | Mean | Scale |
|---|---|---|
| Capability | 2.22 | 0-4 |
| Embodiment | 1.73 | 0-3 |
| Presence | 1.30 | 0-3 |
| Accountability | 1.25 | 0-3 |
| Context | 1.73 | 0-3 |
| Verification cost | 1.68 | 0-3 |
What this means in practice
Roles in this band tend to change shape rather than disappear. The output gets drafted faster and the person moves toward review, judgment and accountability. The useful question is not whether to use these tools but who is trusted to sign off on what they produce.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.
