The future of self-driving? Maybe less like Elon Musk and more like Domino's pizza robots

As companies like Tesla and its CEO Elon Musk come to Austin, Texas, the booming city and new tech hub has grown so much it has struggled to make good on its "keep it weird" motto. But since early June, when residents of the South Congress, Downtown, or Travis Heights neighborhoods order pizza from Southside Flying Pizza, their pies might arrive inside a three-wheeled robot -- the REV-1. But it is no full self-driving Tesla. About two dozen REV-1 vehicles now trundle down the roads of Austin and Ann Arbor, Michigan, where the company behind the robots -- Refraction AI -- first launched in 2019 in a bid to harness driverless technology in a new way. Autonomous vehicles, and their potential to disrupt the way people get around, have hovered on the horizon for years. But the technology hasn't matured as dramatically as early investors had hoped.
