Well you see, if I'm driving too fast and I cause a crash - I might lie and claim I wasn't driving too fast.

The black box, by providing evidence to prosecute me, makes the roads safer for other people as while I'm in prison, I can't cause any further accidents. But it doesn't make me all that much safer, prison is a dangerous place.

> How is the black box a safety feature?

This is pretty obvious. Having a black box helps better understand what happened and what may need to change to avoid future accidents.

This is clearly different than always transmitting my speed and writing tickets without context.

The black boxes from the American Eagle jet and the black hawk helicopter have been recovered and will be used to figure out what happened, hopefully helping to prevent future tragedies.
