Digital License Plates
They’re a thing:
Developers say digital plates utilize “advanced telematics” — to collect tolls, pay for parking and send out Amber Alerts when a child is abducted. They also help recover stolen vehicles by changing the display to read “Stolen,” thereby alerting everyone within eyeshot.
This makes no sense to me. The numbers are static. License plates being low-tech are a feature, not a bug.
