Prediction text
Only 20 million cars needed once FSD robotaxis arrive, down from 140 million | once you have FSD, then you have cyber cabs and once you have cabs, you only need 20 million cars to get everybody everywhere they want to go in the in the country down from 140 million or something like that.
Watch events: Any state/federal retraining-on-displacement law (CA, NY, WA pending); Waymo 1M rides/wk (end-2026); Tesla Robotaxi scaling; NHTSA AV rules
Verbatim quote
once you have FSD, then you have cyber cabs and once you have cabs, you only need 20 million cars to get everybody everywhere they want to go in the in the country down from 140 million or something like that.
