what traffic law? speeding? 80% of drivers exceed the posted limit. that's your standard to criminalize?
ths issue in my post was that the black box also measures braking reaction time. any person over 60 has worse reaction then a younger person. do we use that fact to make criminals out of them in accidents involving injury, that they braked too late or not at all? does everyone have to be able to brake like Jeff Gordon now?
Do you want everyone over 60 to get a free pass for injury accidents they caused? Why bother with a jury?
