It is covered widely that autonomous cars use TBs a day of data. I use a TB of data a month and that data is used across a wide range of videos, downloads, web browsing, and I can look at statistics on where that data is used and where it goes.
Stacey On IOT writes on the mobile edge and goes over the autonomous car use case and where will the edge be.
Moving 4 terabytes of data across 400 cars generates 1.6 petabytes of data a day, which is an obscene amount of data to transfer over mobile networks. Thus, edge processing is already taking place to produce insights required to drive the car, on the car itself.
In addition to much of that data being processed on the car, Vijay said Uber is also creating storage depots with fat connections that can handle the uploads of multiple cars. In areas where a cluster of self-driving cars may overwhelm the network, he suggested use of a mobile data center packed into what looked like a minivan to help process the data.
Part of me wonders if Uber and others talk about all the data for autonomous cars as a way to get others to waste their time. If they are generating 4TB a day now, they aren’t uploading those images now. It would seem like they are collecting lots of data now and running these cars in an instrumented mode.
Flight test instrumentation (FTI) is monitoring and recording equipment fitted to aircraft during flight test. It is mainly used on experimental aircraft, prototype aircraft and development aircraft - both military and civil, and can monitor various parameters from the temperatures of specific components to the speed of the engines. This may be displayed in the cockpit or cabin to allow the aircrew to monitor the aircraft in flight, and is usually recorded to allow the data to be analysed later.
A small modular data acquisition unit
FTI typically monitors between 10 and 120000 parameters - for example temperatures inside the cargo and pressure distribution along the wing. FTI sources could be temperature sensors, pressure probes, voltages, current transducers, potentiometers, strain gauges, aircraft data buses or cameras.[1] These sensors may be digitalized and acquired by the data acquisition system. A cockpit audio recording may also be included. A telemetry transmitter may be added to the FTI to allow real-time monitoring of the tests from a ground-station.

But when planes fly get approved for production they don’t run in this heavily instrumented mode. They did need the instrumentation data though as part of certification to fly.
If we had details on what is in the 4TB of data you would know how much is needed to drive the car vs what is needed to certify the car.
