Goodhart's Law, applied.
It's easy to copy and paste: "When a measure becomes a target, it ceases to be a good measure"
In application Goodhart's Law means that you must also use another measure that more closely matches the desired result.
In this instance, that means that we should also be looking for injuries per X. Where X may be vehicles sold, distance travelled per vehicle, or per person-vehicle, per time, or some other per capita number. As far as I am aware, numbers like this are not easily available or comparable.
