The article suggests they are advocating for a blanket law. Are they saying that anytime an accident happens involving a car and a bike where the driver was at fault it should be a criminal prosecution? Is that the type of society we want? Do we expect accidents to never happen and want to criminalize anything less than perfection?
We have manslaughter laws that allow for criminal penalties when a person's negligence rises to a level of criminality. Accidents happen. Accidents that result in terrible injury and death are tragic. But humans aren't perfect; we get distracted--by things other than cell phones. Not every accident is criminal in nature; and for that we have a civil system that--while focused on monetary compensation--is simply the best we've come up with beyond demanding blood satisfaction.
I guess I wish I understood the debate better.
