Maybe these examples of NZ track crashes are more appropriate.

A mainly a visual display that NZ circuits can be quite fast in places and have relatively high energy crashes or awkward crashes into track hardware so safety might be a fairly important consideration if you want a 'fast' touring car class.

Another consideration is the TCR class. Like the TRS attracting top potential talent for the single seaters. Maybe NZ could attract top young touring car talent for a few races over summer, talent that is backed by sponsors or the deep pocketed Euro/ Asian types(for a few grid places) who want to stay race fit in their off season.
