[AutonomousVehicles] Waymo Relaunch in San Antonio

[pmdonahue2 at gmail.com]

Good evening everyone,

 

Tonight I did a Gemini search to get the latest information concerning the
relaunch of Waymo in San Antonio. It's finally great to have concrete
information concerning their resumption of service in the Alamo City. What
will be interesting to see is if Tesla will launch before Waymo comes back
with Zoox to follow?  Waymo also plans to expand their geofence to include
Stone Oak and the Medina Base areas where we and our housekeeper live  and
put San Antonio on the map as the first Texas City to have Waymo operating
on freeways. They're also supposed to make upgrades to their website. The
information below will go into greater detail. Here it is:

San Antonio Service Relaunch, Freeway Operations, and Expansion Roadmap

Official Policy Response, Projected Timeline Milestones, and Public Web
Accessibility Commitments

____________________________________________________________________________

Direct Message to our San Antonio Community:
We hear you clearly: 'Soon' is not an acceptable timeline, and generic
app-only status updates do not provide the transparency, predictability, or
accessibility our riders-especially members of the blind and low-vision
community who depend on autonomous mobility for daily independence-deserve.
We apologize for the extended pause, mixed messaging, and lack of public web
reporting following the April weather incident. This document provides
concrete milestone dates, detailed geographic expansion plans for Stone Oak
and Medina Base, our freeway integration schedule, and immediate web
accessibility reforms.

 

1. Comprehensive Incident Review & Root-Cause Corrective Actions

The April 2026 Weather Incident: In April 2026, an autonomous test vehicle
encountered rapid flash flooding at an unmarked low-water crossing during a
severe thunderstorm event in the San Antonio area. While no passengers were
on board and no injuries occurred, the Waymo Driver's automated terrain
perception and hydrological threshold parameters did not initiate early
rerouting quickly enough before rising water compromised wheel traction. In
response, Waymo enacted an immediate operational stand-down across the Alamo
City territory.

Corrective Safety Systems Implemented: San Antonio presents a unique
hydrological landscape with extensive low-water crossings, concrete drainage
basins, and localized flash flood zones. Rather than applying a superficial
patch, our engineering and safety teams conducted a comprehensive overhaul
of the Waymo Driver's environmental sensing stack. Key enhancements
completed during the pause include:
. Hyper-Local Flood & Standing Water Detection: Enhanced 5th-Generation
lidar and camera optical depth algorithms capable of accurately measuring
standing water depth, flow velocity, and submerged road markings up to 100
meters ahead.
. Direct Integration with Bexar County Flood Warning System: Real-time
telemetry connection to San Antonio River Authority (SARA) and Bexar Flood
emergency sensor nodes, enabling preemptive geo-fencing and route exclusion
hours before visual flooding occurs.
. Fail-Safe Safe Stop & U-Turn Protocols: Autonomous vehicle programming
that executes a safe multi-point turnaround or elevated curb pull-over upon
detecting water depths exceeding 3 inches, completely eliminating low-water
crossing hazards.

2. Definitive Projected Relaunch Timeline for San Antonio

Milestone Schedule (No More Ambiguity): We acknowledge the frustration
caused by previous 'coming soon' statements and premature app reopenings in
May. Below is our binding operational schedule for resuming public
commercial rider operations across San Antonio:


Phase & Milestone

Target Date / Window

Operational Scope & Service Coverage


Phase 1: Closed-Fleet Calibration

September 15 - October 15, 2026

Autonomous testing with Waymo safety specialists and telemetry mapping
vehicles across Central San Antonio, Pearl District, Downtown, and
Southtown.


Phase 2: Trusted Tester Program Relaunch

October 20, 2026

Invitation of community testers-with dedicated slots for accessibility
advocates, blind and low-vision riders-to resume free autonomous daily trips
in the core zone.


Phase 3: Full Public Commercial Relaunch

November 18, 2026

24/7 fully autonomous commercial service opens to all users via the Waymo
One app across the initial 45 sq. mile San Antonio operating territory.


Phase 4: North & Southwest Expansion (Stone Oak & Medina Base)

Q1 2027 (January - March 2027)

Commercial territory expansion encompassing Stone Oak corridor, Port San
Antonio, Medina Base area, and medical hub destinations.


Phase 5: Full Commercial Freeway Access

April 2027

Autonomous high-speed highway routing without safety drivers along I-10,
Loop 410, Loop 1604, and US-281.

 

3. Detailed Territory Expansions: Stone Oak and Medina Base Corridors

Strategic Priority Areas: San Antonio riders have rightfully emphasized that
suburban and employment centers require autonomous access just as much as
urban downtown cores. Our Phase 4 expansion directly addresses these
critical corridors:

Geographic & Destination Specifics: . Stone Oak & North Central San Antonio:
Coverage expanding along the US-281 North and Loop 1604 corridor. Key served
destinations will include North Central Baptist Hospital, Methodist Hospital
Stone Oak, Canyon Golf Road residential neighborhoods, and major retail hubs
at Village at Stone Oak. Mapping vehicles begin active high-definition
scanning in December 2026.
. Medina Base Road, Lackland Corridor & Port San Antonio: Dedicated coverage
encompassing the Medina Base Road corridor, Port San Antonio innovation
campus (Boeing Center at Tech Port), and connections to Southwest Military
Drive. This expansion delivers vital transit independence to tech workers,
military personnel, and south-side residential communities.
. Medical Center & University Corridor Integration: Seamless routing between
the South Texas Medical Center, UT Health San Antonio, and UTSA Main Campus.

4. San Antonio as Texas's First Autonomous Freeway Testing & Commercial Hub

Highway Integration Commitment: We share your objective of bringing
high-speed highway routing to Texas, matching what we have achieved across
our expansive service territories in Phoenix (including Sky Harbor Airport
freeway connections), the San Francisco Bay Area, and Los Angeles.

Freeway Execution Plan: San Antonio will be the first city in Texas where
Waymo deploys fully driverless freeway operations. Navigating the expansive
Alamo City geography requires high-speed connections across arterial loops.
Our phased freeway roadmap includes:
1. High-Speed Sensor & Merge Validation: Closed-loop autonomous testing on
I-10 West (McDermott Freeway), Loop 410 (Connally Loop), and US-281 during
off-peak hours beginning November 2026.
2. Loop 1604 & Express Connector Mapping: Integration of active construction
zones, managed lane entries, and complex flyover interchanges (e.g., Loop
1604 at US-281 and I-10 Interchange).
3. Commercial Passenger Highway Routing (Target: April 2027): Eliminating
surface-street-only detours, cutting travel times by up to 45% between
Downtown, Stone Oak, San Antonio International Airport (SAT), and Medina
Base / Port San Antonio.

5. Web Transparency, Service Status Visibility, and Blind Accessibility

Accessibility & Information Transparency Reform: Waymo was founded on the
vision of self-driving technology empowering individuals who cannot drive,
including people who are blind or low vision. We acknowledge our failure in
restricting real-time service status solely to the mobile app and failing to
maintain accessible, transparent status information on our public website.

Concrete Commitments: Effective September 1, 2026, Waymo is instituting the
following accessibility and communication protocols:
. Public Service Status & Relaunch Webpage: Real-time operational status,
weather hold alerts, active operating boundary maps, and relaunch milestone
dates will be maintained at waymo.com/san-antonio and waymo.com/status.
. Full Screen Reader Accessibility (WCAG 2.1 AA Compliant): All online
interactive maps, service status banners, and milestone announcements are
coded with robust ARIA landmarks, alt-text descriptions, and structured text
summaries for JAWS, NVDA, VoiceOver, and TalkBack users.
. Direct Community Advisory Sessions: Waymo's Accessibility Operations Team
will host quarterly virtual briefings and in-person vehicle tactile
orientation sessions in San Antonio starting October 2026, allowing blind
and low-vision riders to experience the in-cabin audio cues, Braille
controls, and exterior locator chimes before commercial launch.
. Automated SMS/Email Milestone Alerts: Riders can subscribe to text or
email notifications for territory openings and freeway availability without
having to repeatedly check the mobile application.

Sincerely,
