The 'black box' technology only registers the speed, braking effort, etc when the airbag(s) are deployed, as in an accident. It does not constantly register your speed. While some rental car companies can track your speed and position, it's highly unpopular. I seriously doubt the majority of American drivers will simply roll over quietly and allow this kind of constant-tracking technology to become standard on every vehicle sold (the buyer will be paying for it in higher sticker prices). We've lived without it up to now, accident rates are steadily dropping and there is no demand or real need for a constant-tracking device on every vehicle sold. The current airbag-deployment-triggered devices are more than enough. Going further to track drivers movements, speed, etc will just harrass and really piss off the driving public. Especially me.
