Let me elaborate on that one.
Let's for a minute forget about the accidents. I'm not saying it's not, I'm saying from an engineering point of view.
When you want to make changes you have to have a reason for that. What are the reasons for change, based on our experiences, based on data? It's not what you or I think, or this and that.
You collect data, let's say over five years. You record it, do a root cause analysis, figure out what's going on, and then you put your money where you will get the best value.
We had the legacy cars, we have good-faith cars. As you said, where do we go from here?
If we don't make our decisions based on real fact data nobody can guarantee when the new rules come in, how long it's going to last. You may come back again in two years and want to change it.
