CEO Elon Musk has confirmed that the automaker's vehicles equipped with the AI4 (HW4) chip will be able to achieve unsupervised autonomous driving without requiring upgrades. AI4 Will Be Capable Of Self-Driving On Monday,

Tesla robotaxis finally hit the road in Austin, Texas, in June after years of unfulfilled promises from Musk to deliver driverless cars.

Tesla removed its Autopilot basic self-driving software as a standard feature in the US on new Model Y and Model 3 purchases as the company pushes its more advanced FSD (full-self driving) subscriptions.

There’s another wrinkle in things. Even though General Motors and Ford charge a subscription fee for their hands-free driving assists— SuperCruise and BlueCruise, respectively—it comes with a three-year trial period. Tesla will charge $99 per month after 30 days.

Other Tesla vehicles also struggled to attract buyers, with sales of its X, S and Y models all sinking from the previous year.

Tesla’s robotaxi service has been mostly hypothetical so far, but it’s certainly taking the company’s shareholders for a real ride.

With a struggling core business like this, there's only one way to explain Tesla's price-to-earnings ratio of about 300: The valuation assumes Tesla solves autonomy -- and solves it in a big way that translates into huge sales and profit growth for the company.

This isn't the first time Tesla has faced criticism. A class action lawsuit that was filed in Florida claims that electronic door handles on Model S vehicles from 2014 to 2016 "routinely fail" within years of typical driving. The suit said Tesla "knew or should have known" about the defect.
