Green tweeted that Tesla recently added the name of an Australian and Asian vehicle testing ground to its software.
There are other vehicle testing grounds also listed in the code, he said, located in Europe, China and Korea.
Important tests that benchmark vehicle safety happen at these sites, which have government and industry support.
Now Euro NCAP, Europe’s government-backed organization that evaluates vehicle safety, is investigating Tesla following this suggestion.
The organization has examined Tesla’s software updates to test vehicles and not found any fault, Williams said.
