Talk about editorializing, " this represents the greatest possibility for a mass terrorist attack in human history." This is a common misunderstanding seen in Hollywood movies where just because something is electronic it is assumed it is in constant communication and able to be completely controlled and manipulated by some evil doer. We are no more at risk of this than of Al Qaeda taking control of everyones microwave and burning up all our food so we starve to death.
Also, like most issues, this is more complex then you might think. Just like consumers would like the ability to Buy and use an iPhone with T-mobile some auto owners would like to not be completely held hostage by the auto manufacturer anytime they need work done on their car. This necessitates open standards and carefully thought out standards that make things like aftermarket scan tools and even cool accessories possible while not putting the owner at risk. There is more gray area there than you might think.
