Laws can't satisfy every single edge case. I have to sometimes run red protected left turn lights (very carefully) on my motorcycle because they don't sense it. Sometimes you have to swerve out of your lane due to an emergency, etc.

We have judgement for a reason. I also feel like the current fines associated with various law breaking have the expectation that not all of the behavior will be captured and thus it's rather high. If I got an automatic $5 fine every time I went 10 mph over the limit I might be more amendable to it than if it was $300 each time (as it is now). Again, if I am speeding 15 over in the middle of a deserted highway it's different than doing so in a residential area.

Also per https://en.wikipedia.org/wiki/List_of_motor_vehicle_deaths_i... I would not say ALL of those deaths are caused by "careless driving". In fact the majority is probably due to alcohol, falling asleep, etc. although I suppose you could consider being drunk while driving "careless".
