A Tesla vehicle could also scoop up visible mac addresses, and is equally as capable of doing so as every other wifi-enabled device with closed source firmware.
Android phones have been scooping wifi mac addresses, pairing them with GPS data, and sending that to google for at least 7 years: https://slate.com/technology/2018/06/how-google-uses-wi-fi-n...
Apple probably has an equivalent system.
Privacy-wise, Tesla is shitty but not extraordinarily shitty. Their surveillance capabilities do not differentiate them from among the multitudes. Let's assume maximum maliciousness. Assuming you don't own one, could Tesla track you particularly better than, say, Square? Or Google? Or Palantir? Or Comcast? Or any cell phone company? Or whomever it is that owns the cameras at each traffic light intersection?
Nothing I have said makes light of those other systems and the grotesque data gathering that they do.
Totally agree on the second part.
They were all on stage together, regardless of how they got there. They are all there.
But you're correct, Tesla is yet another among the multitudes with a robust surveillance network
