    - automotive control units: Think about cars being on the highway with
    many fancy features built into their electronics (from their owners),
    which unfortunately are a security risk for the owner and others on the
    road.

I don't think cars depend on software for safety as such.  If a
computer breaks down, the engine mail run badly -- but if you run
out of gas, it might stop entirely.  You can still steer the car.

If someday cars do have computers whose proper functioning is
necessary for safety, we could use airplanes as a policy example.  If
you own a small plane, you are free to change it, but you need to get
the change inspectied for airworthiness.

    - medical equipment: Think what nice features could be implemented into
    these many machines located in the emergency room... Accessible to any
    person who comes by.

Being free to change your copy of a program does not mean you must let
anyone and everyone change your copy.  For instance, the code on my
netbook is all free software, but it is not generally accessible to
anyone but me.
