  • Just like modern cars… I wish there was some kind legislation that would limit phone-home telemetry to emergency service telecommunication frequencies, and be opt-in only. That way any OEM operating under commercial cellular frequencies would thus be unlicensed, and subject to FCC violations and import bans. Like what OnStar was originally pitched as; only auto dialing to 911, and 911 only, if you were unresponsive after airbags deployed. OEM couldn’t use the telecommunication frequencies for anything other than networking with emergency service endpoints on the same VLAN.

    Anything recorded by the vehicle would be required to stay on the vehicle due privacy regulations, like the black box recorder for warranted forensic investigations. OTA updates could also be distributed offline for users to download and flash via USB, like any motherboard bios, so transactions would be write only.





















  • I would also guess the smaller range of hardware revisions is easier to keep track of when considering something as device specific as microphone frequency response curves or approximate intrinsic camera calibration values, thus simplifying the post-processing or data ingestion from an aggregate deployment of recording equipment.

    While Android devices are probably significantly cheaper, they’d vary quite a bit in terms of microphone, camera, and lens manufacturers, not to mention ADCs, gain to noise ratios and cheapest firmware, depending on what the OEM felt like swapping to for that minor product revision.

    Not sure how precise these researchers are trying to calibrate and rectify field measurements, but if they’re using internal phone sensors rather then external AV peripherals, then homogeneity across field computers would simply matters of data uniformity.
