On the Danger of Using Email Addresses as Identifying Information (Humor)

On a lighter note, someone with a similar name to mine just used one of my email addresses to register for the Lexus Remote app. Judging by the email I got, using this email address that I own, I can register for the app and presumably do something about the car behind it. Does Lexus already offer a “summon” feature? Seems like the car is based in the U.S. so it would be good if it was amphibious.
