I have a Mac, so it has things like WiFi and Bluetooth that most Wintel boxes don’t tend to have. (I used to build PCs. I know those motherboards exist, and what it costs over base to get those features. So I know they exist and why they’re not common.) What it does not have is a camera. My MacBook has one, but any site that wants to use it needs to ask permission first. When I say no, it does not see the camera. It’s not saying “I see camera, can I use it” it’s asking “can I use camera?” An answer of no returns the message “no camera.”

I suspect it’s the same with all platforms. Meaning anyone who wants this can use it and the rest of us will just default to identifying sidewalks to train the cars.
