AUSTIN, Texas — Elon Musk said all cars will eventually feature Starlink connectivity, describing satellite internet as the only practical method for delivering high-bandwidth service to the global vehicle fleet.

"All cars will have Starlink in the future," Musk posted on X. "It's the only way to get super high bandwidth to billions of vehicles."

The comment came in response to discussion of a Tesla Cybercab prototype spotted in Texas with a flush-mounted Starlink dish on its rear. Photos shared by an account tracking Tesla developments showed the antenna integrated more seamlessly than earlier temporary installations on test vehicles.

Musk, who leads both Tesla and SpaceX, has long argued that traditional cellular networks face inherent limits in providing consistent, high-capacity connections across vast numbers of moving vehicles, especially in rural or remote areas where coverage is sparse. Starlink's low-Earth-orbit satellite constellation is designed to deliver broadband nearly anywhere with a clear view of the sky.

The vision aligns with Tesla's work on autonomous vehicles and robotaxis. Continuous high-bandwidth connectivity could support real-time data exchange for full self-driving systems, over-the-air software updates, high-definition mapping, and in-vehicle entertainment or productivity features once cars operate without a driver. For a fleet of robotaxis, reliable connectivity would also enable remote........
