It makes you wonder about the specifics:
- Did the 1.5 workers assigned for each car mostly handle issues with the same cars?
- Was it a big random pool?
- Or did each worker have their geographic area with known issues ?
Maybe they could have solved context issues and possible latency issues by seating the workers in the cars, and for extra quick intervention speed put them in the driver's seat. Revolutionary. (Shamelessly stealing adam something's joke format about trains)
