Tesla's much-anticipated launch of its Full Self-Driving technology has been repeatedly delayed over the years. Musk initially promised Tesla's cars would demonstrate full autonomy by the end of 2017. Despite the persistent delays, the Model Y delivery still marks a major success for the company.

Tesla said it completed its first fully autonomous vehicle delivery from factory to customer. A video posted on X shows the vehicle — a Tesla Model Y — leaving the company’s Austin Gigafactory, driving on the highway, passing through suburban sprawl and residential neighborhoods, before arriving at a customer’s apartment building.

In a 30-minute video, Tesla claims a Model Y drove itself from the factory to a customer’s home. But online, not everyone is convinced.
