Attack of the Killer Car Wash
This is not a joke: "A group of security researchers have found vulnerabilities in internet-connected drive-through car washes that would let hackers remotely hijack the systems to physically attack vehicles and their occupants. The vulnerabilities would let an attacker open and close the bay doors on a car wash to trap vehicles inside the chamber, or strike them with the doors, damaging them and possibly injuring occupants."
