What if I buy a used car that has it in it already?

It's the kind of thing the owner would probably keep for themselves when selling the car. It's fairly easy to uninstall - just unplug and remove a windshield sticker.

Eh, maybe a little. But I think most people on this website could buy this but they are clearly incapable of understanding the limits of Tesla's shitty AI. The reasons we haven't heard much about accidents with this are (1) they have like orders of magnitude less users than Tesla and (2) nobody gives a shit about this little company and so media doesn't rush to talk about it.

I'm guessing no-one will give a shit about the company size when first there's a death. We'll see.

More to the point, the kind of person who buys this would not want more known about its limitations than your average Tesla owner.
