Some Chinese-made cars from BYD, Nio and Geely now get stopped before they reach sensitive Bundeswehr sites, over what their cameras and sensors might record.
A connected car might be kept out of one restricted zone while still parking in a lot farther from sensitive buildings.
The push toward a permanent ban on Chinese connected vehicles has been building across several Western governments.
The restrictions apply to any connected car carrying that sensor suite, regardless of powertrain or country of origin.
In October, the US military barred privately owned BYD vehicles from entering Kadena Air Base in Okinawa, Japan, citing security risks tied to the same sensor categories.
