Etymology
Origin of driverless
First recorded in 1840–1850
Explanation
If you spot a car cruising down the road without a human at the wheel, don’t worry — it's not a ghost driving, it's probably just a driverless vehicle. The word driverless means exactly what it sounds like: a vehicle with no one driving it. The word combines driver, someone who drives or controls movement, with the suffix -less, which means "without." Driverless vehicles use technology like sensors and computers to "see" the road and make decisions without a person behind the wheel.
