Tesla recently launched an expansion of its "Robotaxi" service in the American city of Houston, adopting a geofence map designed in the shape of a rocket under the slogan "Houston, we have liftoff." However, field reports from experts tracking autonomous driving fleets have revealed that this map does not accurately reflect the operational reality of the service, as it includes vast areas in the city center where the cars cannot actually operate.
According to Ethan Mikkana, a former Tesla employee and founder of the "Robotaxi Tracker" platform, the new service area in Houston is one of the most "misleading" he has observed to date. Mikkana, who tested the service in the field, explained that the Tesla app rejects ride requests in areas clearly located within the announced geographic range, with a message appearing to users stating that the "location is unavailable" and asking them to move to another point.
Technical Challenges in Routes and Maps
The problems were not limited to service availability but extended to the efficiency of vehicle routing. In one documented experiment, the app offered a 43-minute trip to cover a distance of only two city blocks in the downtown area. The reason for this long and illogical route is the autonomous driving system's attempt to avoid railroad crossings or specific technical obstacles that still pose a challenge to Tesla's software in that area.
Mikkana noted that the system is forced to detour around large areas in "Midtown" and the Museum District to reach a very close destination, indicating the existence of technical "dead zones" within the map promoted by the company. However, Mikkana acknowledged that the driving experience in the areas that are actually available was "very good" and surpassed competitors like "Waymo" in some aspects regarding driving smoothness.
What Changes Practically for Users?
This discrepancy between marketing and reality raises questions about the priorities of tech companies when launching autonomous driving services. While Tesla seeks to present an impressive image through maps with symbolic shapes (like the rocket), the end user faces operational constraints that have not been clearly disclosed. This gap is considered a challenge to the credibility of autonomous service maps, as passengers rely on this data to plan their commutes.
By comparison, reports also identified gaps in "Waymo" maps in Orlando, but they were limited to peripheral areas such as airports, which often require special permits or imminent software updates. In the case of Tesla in Houston, the gap is located in the heart of the urban area, suggesting that the marketing design of the map preceded the technical readiness of the system on those specific streets, which forces users to manually verify the availability of the service before relying on it.
