Ten years after the introduction of Google’s self-driving car, it still shows ads for businesses in other cities. Everyone complains, but we’d be terrified if the ads were too good.

Google wants it to seem dumb so they can keep some knowledge for themselves.

When you arrive, the car makes you sing the grocery store’s jingle to unlock the doors.
