Last October, Tesla rolled out a more advanced hardware suite for its Autopilot semi-autonomous driving program. This hardware will eventually allow for full autonomy, Tesla promises. But in the meanwhile, the technology is being put on a rather short leash. Tesla CEO Elon Musk confirmed this weekend that Autopilot will be rolling out to cars equipped with the company's newest hardware suite, dubbed HW2, via over-the-air updates. This new version of Autopilot comes with Autosteer functionality that is limited to a top speed of 45 mph. Additionally, some cars equipped with HW2 will need their cameras calibrated at a Tesla service center to enable Autopilot capability.
