We lose more than 40,000 people/year to auto accidents. BTW the B-1B uses 1970's technology. Your basic IBM PC running DOS with 640K memory is more up to date and has more memory than the computer that does the bombing on the B-1B.
I believe the Federal Highway Administration rejects that figure as being an acceptable number of deaths and are working toward reducing that carnage.
How? I would guess since most drivers are not trained beyond their experience so the improvement would have to come in a manner that would be beyond the control of the individual driver.
Life saving technolog; ie, much like the airbag, the seat belt, these two ancient lifesavers, recent as they are, are not enough so we press on to other technologies that will force us to live a little longer or die by "an icicle falling on our head".
Or something less violent.(A modicum of jocularity there, See Reply #99)
