They are already flying over some big cities and constantly capturing everything in car-level resolution, then when a "crime" happens they can roll the tape back and see the where the car came from.
A big point from the podcast isn't that the goal is to identify you or your car later as you might think. It's that they can "rewind" the footage and trace where the offender came from and show up at their doorsteps within minutes/hours. It's as much about traceability as identification. A vinyl wrap won't help that.
David Brin has idea after thinking about future making surveillanace unavoidable. The solution is that everybody can spy on everybody else. The problem is that the government and corporations can spy on us, but are immune. I'm not sure if he means it as blueprint or inevitability with the price dropping.
I think he is wrong that everybody spying will help, when everybody discussing online doesn't. But it is useful to think about what world will be like when everybody can surveil.
The #MeToo movement made me realise that we will probably choose constant surveillance for our own protection, rather than have it imposed on us by some Orwellian government.
I'm not saying it's good or bad. But it is inevitable, and we need to adjust to that reality.
