So why would there be only one bus to the steering column?  My car has 
no CAN bus I'm pretty sure and has half those functions so that many 
wires.  Reducing this to two buses should be duck soup.

Using one UI for both secure and insecure functions is problematic and 
should not be done.

Why would any of that have to connect to the secure systems?  If it is 
needed to send a command to not allow the car to start or even to shut 
it down, that command would need a protocol that can not be duplicated, 
a secure protocol through a secure control point.

Really?  What critical emergency tasks are handled by the cell phone 
interface in a car?
