This is old News, but serious nevertheless.

The more software you load into a car the easier it is to take control of it all. One horrifying possibility would be to murder people by programming the computer in the car to drive into a tree or another car at speed. The more cars are automated, the more vulnerable they become. It would be impossible in a Morris Minor, but with all the smart software being written for driverless cars it would become a lot easier.

Would this be a good theme for a detective novel?
