Advanced driver-assistance systems — known as ADAS — help drivers park, stay in their lane or avoid objects using cameras, radar and other electronic sensors. They alert drivers or briefly take control of the car to avoid collisions. One of the first such tools was the ABS anti-skid braking system introduced more than four decades ago that’s now standard. More recent systems include features like emergency braking and automated parking.

What’s the advantage over driverless?
There are a few things:

Keeping humans involved isn’t necessarily a bad thing. Sure, people tend to make more mistakes than a computer, but it’s good to have an actual person ready to intervene if technology fails.

Driverless ethics are a tricky subject, given that robot cars would have to make life-or-death decisions in some scenarios — like choosing which person to crash into if a collision can’t be avoided.

Autonomous driving is far more difficult and expensive to commercialize at scale, requiring billions of dollars in capital.
