One difference between the network in your car and a typical computer network is that all devices in the car trust each other. Therefore, if an attacker can access one computer, they can easily access other computers in the car.
As with any new technology, some aspects of today’s cars make it harder for thieves, and some make it easier. There are several methods of stealing a car that are enabled by today’s technology.
