It isn't about defining what I call simple error, it's about defining criminal negligence. Then it's about proving it and getting a jury to convict. It might work if you could randomly select 12 people like you who are so lily white and perfect that they believe that bad outcomes are all from criminal acts. But most people would not convice someone of something they might see themselves doing, so criminalizing distracted driving, beyond traffic court simply won't work.

We have laws against ****, and women get *****, we have laws against robbery and people get robbed, w have laws against all sorts of behavior and it continues to happen, so it's naive and simplistic to a expect a law criminalizing most accidents would magically prevent them.

In any case, you keep wanting to blame and punish other people when cyclists die. In this case it's because they weren't seen at 1:30AM, but in another thread, it was because a cyclist didn't see a train in broad daylight. In your perfect world, are cyclists ever at fault for anything?
