There are hundreds of dead and injured people that say it's not. Killed and maimed by people who were 100% certain that things were safe for them to break the law.
There is kind of a big difference between thinking there is no one there, and there literally being no one there. And the latter happens way more often.
Now THAT is absolute nonsense. You are either absolutely sure(100%) or you are not(90%). You cannot be both absolutely sure and not absolutely sure simultaneously. This is not schrodinger's red light.
You misunderstand me. Sometimes people think they are absolutely sure, when their car obscures their vision. See, in a car you can't look 360 degrees around you. Cars have blind spots. And so, even when you think you are absolutely sure, you can be only 90% sure, or less, due to incomplete information.
But the example was about "what if you DO have complete information, and it is absolutely safe?"
The fact that you can have bad judgment and kill/maim people even when 100% sure, means that it's morally wrong to do so. In your bike example here could have been a small kid wearing cloths that accidentally camouflage him against the background. You didn't see him even though you were 100% sure. He dashes out into the crosswalk when he is supposed to and you kill him.
Yes, if the Predator happens to be crossing the road... I hit him...
...with my BICYCLE. But he's fine. I don't kill him.
(You can be 100% sure that there is no one for miles on this road)
Quite often in traffic you can be absolutely sure. Take for example when you're crossing the road at Route 66, in the middle of Death Valley. You can look for miles both left and right, and you can say with 100% certainty if any traffic is coming.
And this also happens at intersections, especially if you ride a bicycle. There are NEVER kids wearing camouflage crossing the road! Never! You can be 100% sure that when you run a red light, and there is no one there, that no traffic with pop up out of thin air. Especially if you live in a country with very flat open roads.
But I think you're still missing the point of the hypothetical moral example. The example is not about whether you can be absolutely sure. But it's about whether laws are always morally right... and they are not, because context matters. Law cannot cover every circumstance, and quite often a law can be broken without it being morally wrong.
Take for example when I leave my car at a parking lot longer than the allowed time, and avoid a ticket anyway. Is this immoral? I would say not. But it is still breaking the law.
