Over the weekend, Tesla rolled out a new version of Full Self-Driving Beta to thousands of cars that was so full of safety-critical bugs it was uninstalled by the company within 36 hours. 

The software, version 10.3, rolled out Friday to Teslas enrolled in the FSD Beta program with a Safety Score of 99 or better, a metric that can easily be gamed. On Saturday, Elon Musk tweeted, “Regression in some left turns at traffic lights found by internal QA in 10.3. Fix in work, probably releasing tomorrow.” But that was not the biggest problem with 10.3. A few hours later, he said the company was “rolling back to 10.2 temporarily” after “seeing some issues with 10.3.”
