Those aren't questions that have fixed answers. The data available is pretty far beyond what I'm personally comfortable with though.

One OEM I'm familiar with had such a policy. My org determined that we needed a statistical reference to compare against within a certain area. Some calls were made to the right people and shortly after we had a (mildly) anonymized map of high precision tracks for every vehicle of that brand within the area over some period.
