Tesla says its Houston Robotaxi service area has expanded and is live, with an official map showing the old boundary in white and the new one in blue. If your address was on the wrong side of the line, this is the update that matters more than another futuristic launch video.

Your autonomous future has moved closer. Before celebrating, check whether your front door has made it into the polygon.
