Tesla's expanded Robotaxi geofence in Austin has a very distinct shape. OK, it's a giant penis.

When Tesla kicked off its Robotaxi service in Austin, Texas, last month, it started with a reported 10-20 cars and a fairly small geofenced area in South Austin.

Now, that area has grown, and its shape is a not very subtle message to Tesla's competitors.

As revealed on Monday by Tesla's official Robotaxi account on X, the new area where Tesla's Robotaxis operate is shaped like a giant penis.

To make absolutely sure everyone's in on the joke, Tesla CEO Elon Musk chimed in with a reply: "Bigger, longer, and uncut," he wrote. Tesla's Robotaxi account on X shared the image of the new area with the caption: "Harder, Better, Faster, Stronger."

One would think that Tesla has to be pretty careful about how it expands the Robotaxi service, given that its fleet of Model Ys which are self-navigating the city have been spotted making numerous apparent traffic violations. In that sense, the fact that the company was able to expand the service in this (seemingly careless) way can be viewed as a positive development — or perhaps Musk is willing to risk it all to make a giant penis joke.

For comparison, Alphabet's Waymo covers a roughly equal, but far less penile-shaped area of Austin.

Musk recently announced the Robotaxi project's expansion in Austin, and added that the Robotaxi service may expand to the Bay Area "in a month or two." We shudder to think which shape the Robotaxi geofenced area may take over there.
