Seems I was wrong. However, the Robotaxi fleet is still tiny compared to Waymo's. Jalopnik said the fleet was only 34 cars as of EOY 2025[0]. Waymo had over 2,000 as of September 2025[1].

The website that is sourced from

https://robotaxitracker.com/

176 tracked Tesla Robotaxis vs 51 tracked Waymos in SF, with 1000 claimed SF fleet size by Waymo

90 tracked Tesla vs 134 tracked Waymo in Austin.

They claim their data is incomplete and uses indirect app tracking to guess the numbers

Elsewhere in this discussion someone pointed out that each Tesla robotaxi in Austin is being directly followed by a supervisor in another car. That resource constraint could explain the low number.

I looked it up and two articles sourced a twitter video of an Tesla fanboy influencer claiming a chase car was following his taxi https://x.com/JoeTegtmeyer/status/2014410572226322794
