Waymo Robotaxi Expansion Adds Nearly 250 Sq Miles in Five Cities

A wider map without a new city

Waymo's latest move didn't open a new city. It made existing service areas bigger. The Alphabet-owned company said on October 27 that over the following week it would add nearly 250 square miles of fully driverless territory across Los Angeles, Nashville, Orlando, San Diego and the San Francisco Bay Area.2225 All five are markets where Waymo already runs cars with no one in the driver's seat, and the new boundaries are already in its rider app.2225

Here is where the borders moved. In Los Angeles, service now follows the coast south through Manhattan Beach and Redondo Beach to Torrance.22 In Nashville, the zone reaches farther south and now includes the zoo.2223 In Orlando, coverage on the east side nearly doubles and downtown service grows.22 In San Diego, the map extends north to La Jolla and picks up University City and Clairemont on the way.24 In the Bay Area, the service area now runs from San Francisco down the Peninsula to San Jose and Campbell, and it connects to BART at Berryessa station.22

Waymo did not say how much of the new ground falls in each city or how many vehicles it is adding.2224 Third-party trackers filled in part of that gap. Robotaxi Tracker counted a 53-square-mile addition in Orlando, which brings Waymo's footprint there to about 119 square miles, compared with Tesla's 26.27 Another account puts the Orlando total at 120 square miles and says the expansion takes in City Hall, the Dr. Phillips Center for the Performing Arts and the Orlando Science Center.26 The one-mile difference doesn't matter much. Either figure means Orlando nearly doubled.

Fast growth in young markets

The speed matters more than the total. Waymo opened Nashville to public riders only in April, with roughly 60 square miles covering downtown, Midtown, Music Row and East Nashville.22 San Diego opened to the public on September 1, and reaching La Jolla less than two months later is a big jump.22 Local coverage says the San Diego map nearly doubled. The added area includes Mission Bay, UC San Diego, the VA Medical Center and the UTC area.28

Reports disagree on how big San Diego started. Axios put the launch zone at 50 square miles, while the San Diego Union-Tribune said about 40.28 The cars still have limits there: they stay on local streets, not highways, and airport trips were not offered at launch.28 Residents told a local TV station they had seen driverless test vehicles in Clairemont and Mission Valley before Waymo announced anything. That suggests the company does its mapping and validation well ahead of each announcement.28

The five-city expansion caps a busy October. On October 14, Waymo opened fully driverless rides to anyone in San Antonio, San Diego and Tampa, including San Antonio International Airport.25 On October 21, it began airport pickups at Harry Reid International in Las Vegas, inside a 24-square-mile service area.2325 It also announced groundwork for Toronto, with a 2028 target, and for the Madrid region in Spain.25 Waymo now says it operates in 15 U.S. metros and gives more than 500,000 paid rides a week. In May, it reported 1,400 square miles across 11 cities.22

The clearest reading of this activity is that Waymo has a repeatable process for growing its maps and can now run it in several cities at the same time. Adding territory where a fleet, depots and local teams already exist costs less than opening a new market. It also puts more addresses inside the zone for people who already ride. A BART connection in San Jose and a trip to the Nashville Zoo are not dramatic, but they are the ordinary trips that build daily use.

Tesla is drawing bigger maps too, with few cars in them

The announcement came one day after Tesla greatly enlarged its Houston Robotaxi zone.23 Robotaxi Tracker data shows the zone grew by about 229 square miles, roughly tenfold, and now runs from northwest Houston through downtown to Bellaire. That is about five times the 49 square miles Waymo serves in Houston.27 By area alone, Tesla is ahead in that city.

The fleet behind that area is small. One tally counts 34 Tesla vehicles in Houston, and another counts 39.2227 Mileage data shows the same imbalance more broadly. Waymo averaged 3.90 million rider-only miles a week in the second quarter of 2026. Tesla's best week was 558,000 driverless miles, and Austin accounted for 79% of it.21 Waymo has logged 271.3 million rider-only miles since 2020. Tesla has about 3.11 million since January 2026, which is less than Waymo drives in a single week.21 Tesla's own figures are somewhat higher: it said on its earnings call that it had reached 3.3 million miles.8 Even so, the gap is many times over.

Elon Musk recently said the race against Waymo "was never a real contest," after Tesla's Austin miles topped Waymo's there for one week.2122 Tesla got there by putting hundreds of company-owned Cybercabs into one city. Musk said that fleet had grown about tenfold in a month, and Tesla's AI chief Ashok Elluswamy said the company wants to "swarm Austin with Cybercabs everywhere."21 It shows Tesla can concentrate cars in one place. It doesn't show it can match Waymo across 15 markets. Waymo's smallest tracked market, Atlanta, averaged 250,000 miles a week, about ten times what Tesla's Houston, Tampa, Orlando and Miami zones did combined.21

Tesla's footprint is growing on paper. The company lists seven metros in Texas, Florida and California, and since October 21 it has named Las Vegas, Phoenix, San Antonio and Jacksonville as coming soon, with no dates.5 In the Bay Area, California rules still require a safety driver in every Tesla Robotaxi.25

The FSD timeline moves again

The biggest Tesla news of the month was another delay for its consumer product. On the Q3 call on October 21, Elluswamy said unsupervised Full Self-Driving in customer-owned cars would come around Q2 2027. It will arrive with FSD v15, and it will work only when owners add their cars to Tesla's managed Robotaxi fleet inside existing geofences.26 That is narrower than the promise Musk has made for close to a decade, which was a personal car that drives itself anywhere.29 HW3 owners have already been told their computers cannot run unsupervised FSD, and Tesla has not offered a clear upgrade path.9

The supervised product keeps getting better. Update 2026.38.5.11 brings FSD v14.3.13 to HW4 cars with a feature called Automatic Collision Evasion, and gives HW3 cars a "Lite" build trained using the HW4 model as a guide.3 The release notes say the same model now powers Smart Summon, FSD and Robotaxi.3 The business numbers are strong: 1.74 million active FSD subscriptions, up 67% from a year earlier, and FSD on more than 75% of new North American deliveries.58 The contrast with Waymo is still sharp. Waymo puts driverless cars into a new neighborhood each time its map grows. Tesla's equivalent promise is still a date in the future.

Regulators are reacting, not leading

Rules are being written while both companies grow. On October 23, NHTSA proposed optional cyan marker lamps that would show when an automated driving system is in control.1419 Cars running supervised systems such as Tesla's FSD could not use them.15 The same proposal drops steering-wheel-based turn-signal and beam-switch rules for vehicles built without manual controls. Comments are due November 25.1315 It is one of several updates to federal safety standards meant to make individual exemptions unnecessary, like the one Zoox received in July for up to 2,500 vehicles a year.13

Tesla took a different route and self-certified the Cybercab. NHTSA's audit of that certification became a Special Order requiring sworn answers by October 30.1213 Separately, a defect petition alleges Tesla Robotaxis speed in active school zones. It covers about 1,000 vehicles, and a decision is expected around January 2027.1220 Waymo is not exempt from scrutiny either. NHTSA's July demand for plans to stop robotaxis from interfering with emergency scenes was widely seen as aimed at Waymo, and no result has been made public.13

Local governments want more say. San Diego's City Council voted unanimously in September to ask for more control over autonomous taxis, including the power to keep them out of the airport. Waymo's expansion there still rests on approval from the California Public Utilities Commission.28 In Texas, state law bars cities from regulating automated vehicles at all.20

The takeaway

Waymo's 250 square miles are not a breakthrough. They show a company that now runs its service like a utility and keeps building on a large lead in fleet size and miles. Tesla can draw bigger zones quickly, as Houston shows, but zone size has become a weak measure of progress when a few dozen cars cover it. The next markers to watch are Tesla's October 30 answer to NHTSA, the cyan-lamp comment period, and whether Waymo eventually connects its California service areas into one network. Commentators expect that within about two years.22
