Here are the mass-market brands (excluding exotics and uber-luxury cars) that offer high-level adaptive cruise control and lane-centering steering for 2021. Level 2 is currently the highest level of autonomy you can get in a commercial car. Tesla's Autopilot , GM's Super Cruise, and Nissan's ProPilot are all examples of Level 2 Level 4 and 5 automated vehicles are truly "driverless" - meaning a human driver is not needed at all. The car itself handles normal driving and is responsible for safe responses in Level 2 autonomous cars: Partial driving automation. Level 2 includes advanced driver assistance systems (ADAS) which control both steering and acceleration. The automation only falls short of self-driving because a human sits in the driver's seat and can take control of the car at any time. Level 2 Driving Automation - Partial Driving Automation. Level 2 driving automation applies to vehicles with advanced driving assistance systems (ADAS) that can take over steering, acceleration, and braking in specific scenarios. But, even though Level 2 driver support can control these primary driving tasks, the driver must remain alert and Currently, Kia and Hyundai offer Level 2 technology in some of their vehicles that is best-in-class outside of advanced systems like Tesla and GM Supercruise. What It's Called: Lane Following Assist (LFA) and Smart Cruise Control w/ Stop and Go (SCC) All current systems — including the hands-free versions — are just Level 2 partial automation on the six tiers of vehicle autonomy as designated by SAE International and federal regulators. Level 2 automated driving is defined as systems that provide steering and brake/acceleration support, as well as lane centering and adaptive cruise control. Even if these technologies are activated, the human at the wheel must be driving and constantly supervising the automated features. Level 2 _ Partial Automation. System capability: The car can steer, accelerate, and brake in certain circumstances. Nissan's ProPilot is also level 2, as found in the Nissan Leaf. This has evolved into Level 2+, which enables hands-off driving where legal, and includes Ford BlueCruise, as well as the system on jlH2k.
