I wonder if typical car manufacturers who sell cars to other people will really be able to capture this data, technologically speaking. It's way too much data to send over LTE, so you need to have a bunch of disk space to store it, and then you need your users to be OK with you abusing their WiFi in the middle of the night to send gigabytes of data back, which they won't, because we have data caps. Whereas if you operate a fleet, you can just connect a data transfer cable to the car every night and dump all the data. Obviously you can compress the data; maybe throw away the vision and point cloud data, and just keep the object locations, but is control with already recognised objects the real problem here, or is it the actual recognition part?
