According to antivirus software developer F-Secure, the Cabir mobile-phone worm cannot infect a Bluetooth-enabled Toyota Prius. During a recent test, F-Secure technicians tried to transmit the Cabir.B and Cabir.H worms to a Toyota Prius without success. This puts to rest rumors that Toyota and Lexus cars with Bluetooth capability are susceptible to Cabir infection.
Unfortunately, I doubt this trend of immunity will continue indefinitely. As more retail electronics and are controlled by virus-susceptible operating systems, malware miscreants will increasingly target those systems. Personally I'm waiting for the first toaster virus that burns my breakfast.
