Tesla CEO Elon Musk has recently confirmed that the latest version of Full Self-Driving (FSD) software, v14.3, is considered the final piece of the autonomy puzzle for Tesla vehicles. However, the company is holding off on launching a large-scale Robotaxi service until the next major software upgrade, Version 15, is rolled out.
During the Q1 2026 earnings call, Musk explained that Tesla’s decision to delay the widespread deployment of Robotaxis is rooted in prioritizing safety over rapid scaling. While v14.3 is currently powering Robotaxi operations in cities like Austin, Dallas, and Houston, Tesla has identified significant architectural improvements in Version 15 that will enhance safety and convenience for passengers.
Musk emphasized the importance of not rushing a massive rollout when better software is already in development. He stated, “We’re going to want to finish writing that software, validate it, and release it before going to large scale.” While the timeline for expanding unsupervised operations to a dozen states or more later this year is still on track, Tesla is focused on ensuring that the software is robust and reliable before scaling up operations.
Ashok Elluswamy, Director of Autopilot Software at Tesla, explained that the current Robotaxi fleet is operating on variants of v14.3 that have been deemed safe for initial launch cities. However, the team is looking ahead to Version 15, which is expected to be a major upgrade that will provide a solid safety foundation for Tesla’s global autonomous ambitions.
“We continue to expand based on the v14.3 base for a while until v15 lands,” Elluswamy stated. He described Version 15 as a crucial upgrade that will enable Tesla to handle a much wider deployment of autonomous vehicles. With a focus on safety and innovation, Tesla is poised to revolutionize the transportation industry with its cutting-edge autonomous technology.
