All cars produced by Tesla, including Model S and Model X, will have the hardware.
Model S and Model X cars with the inbuilt hardware are already in production and customers can buy one, Tesla said Wednesday.
But the features possible with the new hardware will be enabled only later through over-the-air updates after testing over millions of miles of real-world driving, Tesla added.
The company is evidently not taking chances after deaths in accidents involving Tesla cars in China and Florida raised some questions about the readiness of autonomous technology.
In the Florida instance, it was confirmed that Tesla s Autopilot technology for driver-assistance was activated, while in the China incident, Tesla said it does not have sufficient data to establish that the technology was engaged.
The company has since then upgraded the Autopilot technology, adding radar as a primary control sensor.
