I went war-driving on a whim today. You wouldn't believe how much personal information your car leaks out. I saw names like "Drew's Chevy" and Oscar's Audi S5".

I locked my car down as much as possible when I got it.

My car WiFi is turned off. I didn't pick up anything at all from my car while doing the wardrive.

If you never connect these to wifi you never get collected

That's not true. I didn't connect to these cars, I was just doing passive scans. These vehicles are constantly sending out their SSID, as is the case with all WiFi.

Untrue. Your hotspot can be configured not to advertise. Clients can then only connect to it if they already know the SSID and enter it manually.

Yeah, but hardly anyone does that - as was made apparent by my 20 minute wardrive. By default, WiFi is constantly shouting "here I am!"
