DETROIT: Tesla is allowing some drivers to use its Autopilot driver-assist system for extended periods without making them put their hands on the steering wheel, a development that has drawn concern from US safety regulators.

The National Highway Traffic Safety Administration has ordered Tesla to tell the agency how many vehicles have received a software update making that possible and it's seeking more information on what the electric vehicle maker's plans are for wider distribution.
