At CES technology mega-show, eyes on driverless cars and the limitations

Crowds of techies will descend on Las Vegas this week for the annual CES technology mega-show, but one innovation may again fall short of long-held hopes: driverless cars.

Autonomous vehicles have long been pitched as the new dawn of transportation and the world’s biggest tech companies have poured billions of dollars into being ready.

Despite steady advances, however, robo-travel has yet to take over the open roads, with even Elon Musk’s best-selling Teslas requiring “a fully attentive driver”, despite the billionaire’s assurances his cars will soon be autonomous.
