Just two weeks ago, I was almost creamed by a lady talking on her cell phone and blowing through a red light at about 50 mph. Now, I'm not particularly interested in the number crunching like you have done. I'm satisfied with saying someone could be involved in an accident while running a red light because it happens. Maybe not 15x per day at the same intersection, but I noticed that you didn't take into account the number of cars hesitating on a green light and waiting/watching for the red light runners and inattentive drivers to clear the intersection. I'm not sure how you could calculate that figure but it's certainly a factor in preventing those red light runners from being a bigger accident statistic.
Cheers, my dear.
Big Brother is counting on you.
All human life could be dangerous. People die laying in bed. If our endeavours become so fear inducing then humanity has had it.
Put the fetters on yourself, please spare me and my though.
BTW are you a woman?
