Blue Cruise Active During Deadly Crash in Texas

exactly

i posted some trends and video from my early experiments here:

Yup. The radar feeds the IPMA (or comma) the point cloud data (super simplified view of the environment, those are the dots you see in the vid), not actual radar data which is massively data intensive (The F35 captures ~1TB of data per hour for instance with its sensors and that's with some of it being processed). With 4D radar it's imaging everything. Combine it with persistence and you get a HUGE security vulnerability because it's building ultra high res GPS-sync'd terrain/structure data that can be used in military applications. The western world is sleeping on this issue (chinese autos) -- this is just as big of a deal as tiktok.

4D radar w/ persistence (memory) mapping a city -- imagine 10s of thousands of cars doing this and calling home to upload. This is 3D data, color indicates height.

4D radar in use


These systems are light years ahead of what we've got which produces a couple cloud points per vehicle (that's not stationary), ignoring everything else.

Not worried about Tik Tok... seriously... it's entertainment, not critical info.
Any idiot posting sensitive personal info on Tik Tok needs to be smacked with a brick.

As for 4D mapping... China can already get better imaging info from satellites.
A satellite can see more than what the general public can see driving around.

SAR sats have the same problems traditional imaging sats do in that the information is only live to it passing over. Vehicles at scale are almost a persistent surveillance platform with radar, imaging, and signals intelligence. Now what spacex and northrup are developing will be a continual SAR capability in the form of a LEO constellation of multi-capability platforms. Imagine a starlink constellation with SAR and other elint / imaging capabilities, and oh yeah, it's also a communications platform w/ sat-to-sat laser datalinks (a redundant space based internet).

Pre ai rush we had a TMI problem (machine learning was always a thing, but required significant discrete code)-- when you're watching everything, you have to make sense of the relevant data while retaining data that may have future applications (ie: the FBI retaining encrypted communications because one day it won't take thousands of years to crack a single message), but also discarding useless data -- storage isn't infinite. Now when you use vehicles, the owner is buying the platform for you while also providing a revenue stream. They're even so kind as to put it on wifi and allow the data to be transmitted back home while the vehicle's onboard computers process the data at the edge in whatever manner is required. When it comes to sensitive areas, controls must be in place.

Given the NSA's access to the backbone across T1 providers, often taking up 1/3 of their facilities, I have no doubt they're scraping the metadata. There's still methods of subverting those processes with the resources of a nation state.
