According to the Society of Automotive Engineers, there are six levels of self-driving vehicle technology, ranging from Level 0 (no automation) to Level 5 (full automation).
Currently, vehicles that utilize automation features like Tesla's Autopilot are classified as Level 3: Conditional Driving Automation. Something like the cruise control feature found on most vehicles is considered Level 1 Automation, or Driver Assistance.
There are currently no fully automated vehicles available for consumer purchase. Some countries, such as Sweden, have launched pilot programs with fully automated freight vehicles, but even there the vehicles are still rare. Perhaps the most famous example of a fully autonomous vehicle is the Google Street View car. However, all of these autonomous vehicles are owned by large companies and often still utilize a human driver for emergencies.
