Robotaxi Reached Miami — What Four Live Metros Do (and Don't) Mean for Your Referral

As of July 2026, Tesla's robotaxi service covers Austin (244 sq mi), the Bay Area (890 sq mi), Dallas (31 sq mi) and Houston (25 sq mi) — 1,190 square miles combined — with Dallas and Houston open to the public for unsupervised rides. That month the service expanded to Miami, Florida, its third state. Reporting puts the fleet's total at nearly 700,000 paid miles, with 500-plus vehicles running between Austin and the Bay Area and that count roughly doubling monthly. Tesla's original H1 2026 plan had also named Phoenix, Orlando, Tampa and Las Vegas.

Why this is a good moment for a plain correction

We get versions of this question from readers: does a referral code get me access to robotaxi rides, or a discount on them? No. The referral program's buyer benefit is a three-month trial of Full Self-Driving (Supervised) on a personally owned Model 3, Model Y or qualifying Cybertruck — a driver-assist feature that still requires an attentive driver at the wheel. Robotaxi is a separate, unsupervised ride-hailing service Tesla operates directly, in a small number of metros, with its own fleet. They share underlying software lineage; they are not the same product, and a referral code doesn't unlock or discount either one.

What the expansion is a real signal of

The growing metro count and paid-mile total are a genuine, sourced indicator that Tesla's FSD stack is racking up real-world, unsupervised operating hours beyond what any single owner's Supervised trial could show. If you're weighing whether the referral's three-month Supervised trial is worth having on your own order, this is useful context for how far the underlying technology has come — it's just not a preview of what your own car will do unsupervised the day it's delivered.

Reading the numbers honestly

Two of the figures above are reported constantly and are easy to over-read, so it is worth saying what each one is.

Cumulative totals only go up. A paid-mileage total is an all-time count, so a bigger number later is not news by itself — it is arithmetic. What would be informative is a rate: miles per week, or rides per vehicle per day. Those are not published, which is why a growth claim about this service is only meaningful with two dates attached to it, and why we date ours.

Service-area square miles measure permission, not usefulness. A metro's coverage figure describes the polygon the service is allowed to operate inside. It says nothing about whether that polygon contains your home, your office, or the airport — and a large area that misses your two everyday endpoints serves you worse than a small one that includes them. The only test that answers your case is whether the app will accept a pickup at your address, which takes a moment and beats any square-mile total.

If you are ordering a car, here is the part that matters

None of this changes what you should do at checkout, and the sequencing is the whole of it: open the referral link first, then configure, then confirm the benefit appears in the order summary before you pay. The robotaxi expansion is context for how the software is progressing; it is not a term of your order, and there is no version of it that adds to or subtracts from what your referral link is worth.

What it doesn't change

It doesn't change the referral trial's length, its eligible models, or how you claim it — link first, then configure, then check the order summary before you pay. And living in one of these five metros doesn't add anything to, or subtract anything from, the referral benefit itself; the program is national, not tied to robotaxi service areas.
