Standardizing on sensors and communication protocols can only be a good thing, and the talks about making an "open" self-driving platform are enouraging. Time will tell if it's going to pan out and whether the need for quotes around open.
We are also going to need standardisation on reporting of car use to Governments. If we are no longer going to fund roads through fuel taxes, we need some other mechanism to do it. Proper charging of road use would unlock efficiencies for the road network overall.
Dunno about other places, but in New Zealand commercial trucks mostly have voluntary GPS tracking/logging to estimate their road mileage for road levies. (IIRC because they can subtract mileage travelled on private roads, but the per-km rate might be lower too.)
For most purposes though, a few linked to odometer reading, measured at mandatory "car health check-up" time and maybe amortised over the intervening period would be just fine, and require no new tech or tracking. Maybe tie it to insurance somehow?
