Community Data Shows Waymo's Monthly Fleet Growth Exceeds Tesla's Entire Robotaxi Fleet
On October 31, aronchick, a former Waymo/GitHub executive, published community-tracked Robotaxi fleet data, arguing that Waymo and Tesla are simply not in the same league. The post sparked a back-and-forth with Robert Scoble, with the core dispute centering on how fast each company's autonomous taxi service is scaling.
Confirmed
- According to the dashboard shared by aronchick, Waymo's official global fleet has surpassed 4,000 vehicles; over the past 90 days, the fleet grew from 1,596 to 1,904 vehicles, a net gain of 308 (covering select cities); Waymo has logged 3,616 cumulative trips (across 1,793 vehicles).
- On the same basis, Tesla's entire Robotaxi fleet is roughly 587 vehicles, of which about 425 are in service in Austin.
- Based on these figures, aronchick pointed out that Waymo's net vehicle additions last month exceeded the size of Tesla's entire Robotaxi fleet, and its paid-ride growth also dwarfs the competitor's — something he found stunning.
- Robert Scobleizer responded that both companies are growing exponentially, but catching up to the exponential leader is extremely hard; he still stands by his prediction that Tesla will overtake Waymo next year.
Why it matters
- This comparison is the first to lay out the scale gap between the two Robotaxi operators with quantified, community-tracked data, showing that Waymo currently holds a clear edge in both fleet size and expansion speed.
- The debate also reflects the polarized expectations over whether Tesla can quickly catch up on cost and production capacity — Scoble's "overtake next year" prediction versus aronchick's data-driven view will continue to be tested by future numbers.
- Note that the data comes from community tracking rather than official disclosures, and Waymo's 90-day figures only cover select cities, so the absolute numbers may underestimate its true scale.
