Robotaxis vs. human-driven mobility (watch)
watch window since 2026-09-03
Tesla began public Cybercab rides in Austin on 2026-09-03 (about 45 cars; over 300 by 2026-10-10). Ride-hail fell (UBER about -3 to -4% by 2026-09-08, LYFT with it); TSLA fell 6% on a weak event. Purpose-built robotaxis push cost per mile below human-driven ride-hail. Scoreboard only: no second-order prior reaches 0.35.
