Either the components share an OS instance, in which case what I wrote goes, or the OS governing the
radio app is different from that governing the safety-critical components. In the latter case, there
will be no access from the root permission over the radio app to root permission over either the
network or the safety-critical components. The radio could try to mount a DoS attack on the network,
but as far as I know the existing automotive-network protocols defend adequately against such a
possibility.

I know these assumptions/conclusions can be violated, but only on pain of negligence/gross
negligence. If we are talking automotive, doesn't product safety come in here?
