The first thing I would say is that you can always improve. Until no children who are in crashes suffer any injuries or fatalities, there's always room to move. Given that we're talking about Canada's children, it's always worthy of further investment, time and innovation.
Even the compartmentalization theory has changed over the years. I know that engineers have spent lots of time investigating and testing different ways to make the compartments safe. We still see a lot of injuries from other things that are potentially related to the compartments. I think with one of the other committee members we were talking about potentially hitting stanchions and other metal things within the bus.
There certainly are a lot of places where we can work to minimize injuries, mitigate the injuries they have or prevent them altogether. There is definitely a lot of work to do from that end. As for how that work gets done and what it looks like, that's not my area of expertise, but I still see kids who get hurt on school buses and so on. Until the day when I don't see those anymore, there's room to move.
