#FollowTheLeadTrader Tesla is partnering with Chinese tech giant Baidu to improve the performance of its advanced driver assistance system (ADAS) in China, Reuters reported, citing people familiar with the matter.

In recent weeks, Baidu has sent a team of engineers from its mapping team to Tesla’s Beijing office to work on improving the integration of Baidu navigation data, such as road surfaces and traffic signals, into Tesla’s Full Self-Driving (FSD) software version 13, the people said.

The people did not specify how many engineers were sent to Tesla or whether they would remain there, but said the goal of the project is to ensure FSD V13 has more accurate and up-to-date information about Chinese roads.
