Tesla Reports 1.74 Million Self-Driving Users, But Definition Sparks Debate

As electric vehicle manufacturers compete to define the value of software-as-a-service, Tesla has released its latest quarterly data highlighting the growth of its autonomous driving software. The company announced that it currently maintains 1.74 million active Full Self-Driving subscriptions, representing a 67 percent increase from the same period in the previous year.

The definition of these active subscriptions is central to the current discussion, as the metric aligns with the terms of the 2025 CEO Performance Award. According to a footnote in Tesla’s Q3 2026 shareholder letter, the count includes vehicles where the software was purchased upfront as well as those on a monthly subscription plan. Consequently, owners who bought the feature outright, some several years ago, are included in this total as long as their vehicles remain active, with only free trials excluded from the figure.

This counting method has significant implications for Tesla’s leadership compensation. One of the milestones required for Elon Musk to earn his 2025 pay package is reaching 10 million active FSD subscriptions. However, critics note that hundreds of thousands of these counted users were sold the expectation of unsupervised self-driving capabilities, a feature Tesla has yet to fully deliver. Tesla stopped selling FSD as a one-time purchase in February 2026, shifting new customers to a $99 monthly model in the United States, while retaining the historical upfront buyers in the active count.

In the same shareholder letter, Tesla reported that more than 75 percent of new deliveries in North America included FSD subscriptions during the third quarter. The company described this as a nearly twenty percentage point sequential increase and stated its belief that the software is driving demand in available markets. However, the letter does not specify whether this attach rate includes introductory offers or how many of those buyers continue payment after the initial period, leaving some ambiguity about long-term retention.

Tesla’s progress toward the 10 million milestone appears gradual. The company added 260,000 net FSD subscriptions in Q3, its best quarter to date. If Tesla maintains this pace, it would take approximately eight years to reach the target. At the average rate of the last 12 months, which was about 700,000 per year, the timeline could extend to nearly 12 years. The compensation award runs until 2035, providing a long window for these goals to be met.

The broader context of the pay package includes 12 tranches, each requiring specific market capitalization and operational milestones. As of June 30, Tesla considered only the 20 million vehicle delivery milestone to be probable. Other operational targets include 1 million Optimus robots and 1 million robotaxis in commercial operation. The company’s cumulative delivery figure, now at 10.2 million, also follows the pay package definition by including unsupervised robotaxis placed into commercial operation.

While counting outright buyers is not inherently incorrect, the presentation of this total as a sign of momentum has drawn attention. The definition was established to match the compensation package rather than to provide investors with a clear view of recurring revenue. Tesla knows the exact number of customers paying the monthly fee, but it has not disclosed this figure since reporting 1.28 million active subscriptions in April.

Looking ahead, the 75 percent attach rate remains a key indicator of the software’s commercial viability. If Tesla can sustain this level of uptake for a $99 monthly product, it would represent a substantial new revenue stream. Investors and analysts will likely focus on retention data in future reports to determine how many North American buyers who started subscriptions in the second quarter are still paying today.
