Tesla / FSD by the numbers

FSD, by the numbers.
Sourced, dated, plain.

How big Tesla's Full Self-Driving (Supervised) is, how fast it is growing and where it works. Every number says who published it and when, and where Tesla has not published one we say so.

Active FSD subscriptions

Cumulative FSD miles

Tesla's chart ends just above 15 billion on an axis to 16 billion. Tesla's text gives no exact figure, so this is read off the chart and could be out by about half a billion.

The ratio is our own calculation: active subscriptions divided by cumulative deliveries, which Tesla defines as all new vehicles delivered to customers plus any unsupervised Robotaxis placed into commercial operation. Older cars leave the fleet and some owners use FSD on a car they bought secondhand, so it is a proxy for take rate, not a figure Tesla reports.

Billions of miles, measured from Tesla's chart. Approx. from chart Tesla, 21 Oct 2026 →

Tesla's chart ends at roughly 15 billion cumulative miles in Sep 2026, close to 10 billion of them in the last year by our reading. Nearly all are on V12 and later, which is why the red band dominates.

Tesla's Q3 2026 deck draws this chart (axis to 16 billion) with no data labels, and the text gives no exact total. We measured the chart at each quarter tick, and checked the readings against the same chart in the Q1 deck: they agree to about 0.1 billion. Every value here is still approximate, likely within about 0.5 billion. The blue band is FSD miles on V11 and before; the red band is miles on V12 and beyond.

These are cars Teslascope has seen on each build: owners who connect their car to Teslascope, a self-selected sample that leans to enthusiasts and to North America and Europe. In our stored snapshots a build's count almost never falls, so we treat it as a running total of cars seen on that build, not a share of cars on it today. Other trackers follow different cars and can give different counts.

How to read the numbers

Every figure on this page carries one of these labels, a date and a source.

  • Disclosed Tesla or a regulator said it in a document we opened.
  • Reported A journalist, analyst or tracker found it. Tesla has not confirmed it.
  • Our estimate Our own arithmetic on disclosed numbers. Shown dashed or marked.
  • Approx. from chart Read off a chart Tesla published without exact labels.
  • Target A stated aim or date. Not a result.

What changed

Corrections are shown here, never silently rewritten.

  1. Update Added the cumulative FSD miles chart (read from Tesla's deck chart, marked approximate), the Teslascope build charts (running totals of cars seen on each build, and new cars per day) and the FSD release timeline.
  2. Update Page created. Adoption figures are taken from Tesla's Q1, Q2 and Q3 2026 shareholder decks; countries come from our global FSD tracker data.
