this is pure wishful thinking.  people personally modifying software in their 
car are not going to go get it recertified.

none of your scenarios are applicable to the issues Thomas raised.  public 
safety is significantly more important than a handful of hackers here.  i'm 
not going to knowingly subject myself to a medical device that emits radiation 
(e.g. x-ray machine) that allows anyone to modify it.  that sucker had better 
be locked down to prevent any uncertified (e.g. signed) software 
modifications.  companies that have access to the hardware capabilities to 
prevent this (i.e. secure boot) and dont implement it are blatantly negligent.
