Automated License Plate Readers (ALPRs) are AI-powered cameras that capture and analyze images of all passing vehicles, storing details like your car’s location, date, and time. They also capture your car’s make, model, color, and identifying features such as dents, roof racks, and bumper stickers, often turning these into searchable data points. These cameras collect data on millions of vehicles—regardless of whether the driver is suspected of a crime. While these systems can be useful for tracking stolen cars or wanted individuals, they are mostly used to track the movements of innocent people.

I wonder if water balloons/sandwich bags filled with that stuff might be similarly useful.

As soon as it leaves the pressurized can it expands and then hardens in less than 30 seconds, so it wouldn't really work in balloons or sandwich bags

But a Google search says it doesn't expand without exposure to moisture?

If it's pumped into water balloons and the water balloons are kept sealed, I wonder if it would still expand.

Hm, interesting. I've never tried the balloon thing to be honest. I guess it normally uses the humidity in the air, because I never had to add water when I used it in the past
