The robotaxi penny-a-mile bet
ARK Invest models a driverless ride at 20 cents a mile from Tesla and 40 from Waymo by 2030 — but the number worth watching is today's: Tesla's live robotaxi fleet already runs about 35% cheaper per mile than Waymo's.
A human-driven rideshare in the US costs roughly $2.80 a mile. ARK Invest's autonomous-ridehailing research projects that by 2030 a Tesla Cybercab ride could fall to about 20 cents and a Waymo to about 40 — a collapse the firm credits to Tesla owning its own production line and skipping the expensive LiDAR sensors Waymo bolts on.
Tesla's current Model Y robotaxi fleet operates at just over $0.60 per mile, already 35% cheaper than Waymo's current cost exceeding $1.00 per mile. — ARK Invest
Treat the 2030 figures as what they are: output from an investor-facing model, from a forecaster with a long record of bullish projections, recirculated here secondhand. The grounded number is the one already on the meter. Tesla's live Model Y robotaxi fleet runs at just over 60 cents a mile; Waymo's exceeds a dollar. That ~35% gap is measured, not modeled — and it exists before any of the projected drop arrives.
If the gap holds as both fleets scale, the cheaper per-mile cost decides who can blanket a city first. The forecast is a guess; the head start is real.
