Detroit - Tesla says an update to its Autopilot system will disable automatic steering if a driver doesn't keep their hands on the wheel.
Version 8.0 of Tesla's software began moving over the Internet to its electric vehicles on Wednesday (September 21) night.
Improved tech
Earlier versions warned the driver and slowed the car to a stop if no hands were detected on the steering wheel. It's unclear if the cars will still do that. Automatic steering won't resume until the car is parked.
READY: 'Major improvements' planned for Tesla autopilot
The new version of Autopilot also relies more on radar than cameras. Tesla says the change should help avoid crashes like the one that killed a driver in Florida in May.
Tesla says the software also will move the cars around slower vehicles that are partially off the right side of the road.
