NHTSA levels: [1] Level 3: "Vehicles at this level of automation enable the driver to cede full control of all safety-critical functions under certain traffic or environmental conditions and in those conditions to rely heavily on the vehicle to monitor for changes in those conditions requiring transition back to driver control. The driver is expected to be available for occasional control, but with sufficiently comfortable transition time. The Google car is an example of limited self-driving automation."
Tesla's old system was Level 2. Google and Volvo have level 3 in test. Tesla's new system is supposed to be Level 3. There's a bright line between level 2 and 3 - NHTSA says that at Level 3 and above, the manufacturer is responsible for accidents and cannot blame the driver.
