Apparently change is coming. My new GMC work truck came with an hour meter located within its engine menu. It was included as standard OEM equipment. They’re probably monitoring because of the increased rate of catastrophic engine failure that GM has experienced with its 8 cyl AFM/DDM vehicles. It’s unfortunate that reliability has degraded so badly due governmental restrictions.
Hour meters are nothing new. ECUs have been recording data like that for a long time now (and a lot more). The operator just can’t see it in a lot of cases, but mechanics can if they use diagnostic tools. Things like hour meters, key cycle counters, data recorders, etc. can and are used to help determine the validity of warranty claims when foul play is expected. That data can also be used against the operator in some accidents, and now some data is being sold to insurance companies.
