because if somebody is able to physically sit inside your car, altering 
the code in a micro is the only way to cause the car to crash.
To me this is like saying that a trusted person inside your LAN is able 
to really screw up your computer system.

If somebody is inside the car your screwed, If they have physical access 
to the wiring of the car your screwed, can bus hack or no.

The traditional IT solution of a firewall is appropriate to protect the 
cars electronics from outside attack over wireless connections, and one 
would hope this is implemented.
