How the count works

Registered is not operating

Since 2026, a company that wants to run vehicles in Texas with nobody at the wheel needs an automated motor vehicle authorisation from the Texas Department of Motor Vehicles, under Senate Bill 2807. Each authorised company lists the vehicles it will use, by VIN. Those lists are what this site counts.

A vehicle on the list is allowed to operate. It might be carrying riders, hauling freight, parked in a depot, running tests or driving with a safety operator. The register does not say which, and it lists no cities, plates or service areas. Read every number here as “vehicles the company has registered in Texas”. Never read it as “robotaxis on the road tonight”. Nobody publishes that number.

Where the numbers come from

The TxDMV TxMCCS lookup is public. For each authorised company it shows the legal name, authorisation number, status and date, and a paged list of VINs with a total. The page loads that from a public JSON interface, and EVwire reads the same interface. The DMV offers no bulk download, no documented API and no history.

The DMV also publishes a dated AV Program Report. The edition with data as of Oct 29, 2026 lists 17 companies and 3,164 vehicles, including 1,259 for Waymo and 1,080 for Tesla. The live lookup showed 1,297 and 1,302 at Nov 11, 2026, 3:28 a.m. CT. EVwire uses the report to check that it is watching every company, and the live lookup for the counts.

How often

• The tracker reads every company’s total every minute, one small request each.
• When a total changes, and at least once an hour, it reads the full VIN list and compares it with the previous one. Added and removed VINs are logged with the time they were first seen.
• A snapshot is stored whenever any number changes. Every page shows the time of the last check.
• Requests go one at a time, carry an identifying user agent and back off when the DMV’s server is slow.

History

The DMV shows only the current list. EVwire’s own snapshots start at Nov 9, 2026, 11:28 a.m. CT. A company’s authorisation date is a dated fact about the company. It says nothing about fleet size on that day.

The Tesla vs Waymo chart stitches three sources, each marked on the point. An official earlier count comes from the TxDMV AV Program Report, data as of Oct 29, 2026, which lists 1,080 Tesla vehicles and 1,259 Waymo vehicles, drawn from TxMCCS. From Nov 9, 2026 the points are EVwire’s own checks of the same register. Between those dates, and back to May 28, 2026, the points are historical checks published by Texas AV Tracker, a third-party poll of TxMCCS. Each of those points is credited as Texas AV Tracker. The chart does not use figures from other unofficial trackers. The two earliest Tesla figures in that series (42 vehicles on May 28 and June 2) are counts without a VIN list in the tracker’s history record; later Tesla points, and every Waymo point, include a VIN list. The lookup itself returns a current total and a list of VINs, with no registration date for each vehicle, so a complete daily history cannot be rebuilt from the source. Archived copies of the TxMCCS pages in the Wayback Machine are the search-form shell only; they do not include the vehicle counts, which the live site loads after the page opens. No earlier official program report, and no Tesla or Waymo statement of a dated Texas register count, was found.

Finding the companies

The lookup only answers searches by company name, and the DMV publishes no complete list in machine-readable form. EVwire searches a list of known and likely names every day and adds any authorised company it finds. That search missed two freight companies, Atlas Energy Solutions and International Transport Engineering, until the DMV’s report was checked on Nov 10, 2026. Both are now tracked, and the search list is longer. The jump in the total that day, from 3,359 to 3,404, came from adding them. It was not a change in the register. The changelog records it.

Models

The register lists VINs only. Make and model come from decoding each VIN with the NHTSA vPIC decoder. That is how the tracker splits Tesla’s Model Y from the Cybercab, and Waymo’s Jaguar I-PACE from the Ojai. Where the decoder gives only the make, the model is taken from the company’s own description of its fleet, for example the Volkswagen ID. Buzz for MOIA.

The dot drawings

On the home page and in the fleet chart, each dot is one registered vehicle. The dots are not positions: the register lists no addresses.

Every side profile is traced by EVwire and drawn to scale, so vehicles compare in size. Semi tractors share two drawings, one for Peterbilt and Kenworth units and one for Freightliner, International, Volvo and Western Star units; Gatik’s Isuzu trucks share one box-truck drawing. The register does not say which cab or body each vehicle has. These are drawings for recognition, not engineering drawings.

Use groups

Passenger and freight are EVwire’s labels, based on what each company does in Texas. The DMV does not classify. Nuro is counted as passenger because its registered vehicles are Lucid Gravity SUVs and Toyota Priuses, test cars for a planned robotaxi service.

Known gaps

• A vehicle removed and re-added between two checks would not show up as a change.
• If the DMV changes or withdraws the lookup, the counts freeze at the last check and the pages say so.
• A company the name search has not found is missing until it is found. The DMV report is the backstop.
• Shares are rounded to one decimal place and may not add to exactly 100.0%.
