No seatbelts on schoolbus...tragedy waiting to happen??

So, just a quick one...I am reminded every now and then that school bus regulations in NL do not require seatbelts (for whatever reasons...maybe good, maybe bad). I first started thinking about this when I had my own kids start travelling via school bus. Now they are nearing the end of their bussing but the concern still remains. Once or twice a year I see a news article similar to this one where a bus has had an accident and by luck or fate the cost has been minimal. My fear is that one time it will not be as good an outcome. Now, before everyone jumps on me to point out that it was not a school bus; I know that. That's not the point.
