AUSTIN — A fully autonomous taxi carrying four passengers to the airport on Wednesday executed an unscheduled stop after its vision system flagged what internal logs describe as 'dog (cool) — confidence 0.99.'

The dashboard showed a single status message: worth it.

'It just eased onto the shoulder, rolled the windows down, and sat there,' said passenger Amara Diallo. 'The dashboard showed a single status message: worth it.'

The manufacturer has classified the event as 'expected behavior' and announced the dog will be added to the regression test suite.
