My car was in service when it received this release, here is what i think is happening. The vpn to the mothership is causing the tests to be skewed. Logic I am in the Saint Louis MO region, my test above show Los Angles server, when I connect to Wifi it shows Chicago. See below,
I read somewhere that openvpn was in use. Good odds some, all, or most, traffic goes through a server at a Tesla datacenter. It must make things fun for China. Hopefully they are not trying to pipe all traffic through California or that would pretty much guarantee a poor experience.
