The potentially to reduce the amount of death and serious injury we currently experience is a great goal. I have always found our objection to new ideas that it has a drawback and will ignoring the drawbacks of the current system to be poor reasoning. It is often related to an attachment to the familiar and reluctance to change.
It also relates to our psychology where we often see mistakes of commission as more harmful than omission and then we equate doing the same thing we did before as the assumed behavior and somehow not something we chose (which of course is not accurate, it is an act of commission even if it is the same action as before but psychologically we mistake this relation).
It also related to our legalistic thinking to blame individuals, even when that is not sensible as systems are more responsible for the results. This will be one of the challenges to a safer transportation system – the desire to assign blame in the same way we did before. The delay of safer solutions because lawyers don’t like the new system would be a shame, but is possible. While a delay is possible I don’t think they will be able to prevent a safer transportation solution from becoming a reality.
