The second-order effects are not the fault of the regulators trying to make cars safer
This is where you’re losing me. The second-order effects are within the purview of those regulators and should have been addressed in-hand with the mandate.
Why would the automakers be willing to comply with safety regulation but disregard telemetry regulation?
From an engineering perspective, tying the backup camera to the CAN (and by extension, telemetry units) dramatically increases the possible modalities of failure.
The two are absolutely connected.
