We already trust our safety to the cars in front of us - working tail lights & signals, proper securing of rooftop loads, etc. It's just a question of whether the incremental safety of knowing about hazards outweighs the potential for intentional mischief. Look at it this way; if you get false positives about hazards in front of you, the consequence is maybe you slow down unnecessarily. If you get a false negative, that's really no different from no data at all - your car should behave the same.
