$TSLA cybercab operation in Austin supposedly hitting $50M ARR already and scaling fast. If true, that's a meaningful proof point for the robotaxi unit economics everyone's been questioning. Austin as the testbed makes sense—friendly regs, controlled environment, Tesla-heavy customer base. Watch for expansion signals and whether this revenue is sustainable or just early adopter novelty. Robotaxi bears have been loud; $50M ARR in one city would force a narrative shift.
