LAS VEGAS — The throngs of technology enthusiasts have gone home. The elaborate displays in the convention center have been dismantled. The self-driving technology demonstrations have largely ceased.

But weeks after CES, Aptiv's autonomous vehicles — with their signature orange hubcaps — remain a fixture on the Las Vegas Strip.

The global automotive supplier has staked permanent roots in Las Vegas. The city has become an operational hub for Aptiv, which keeps roughly 75 self-driving vehicles on public roads here.

Self-driving technology was pioneered in the deserts south of the city, and Aptiv's work is ushering in the next chapter in the automated-vehicle era within a 20-square-mile area inside the city — getting that technology into the hands of paying customers.
