Had never heard of these plates. At least the current models may well make the problem worse:

> "In addition to the flexibility of the display, the digital plates also sport a tracking device that will alert the police to the location of a stolen vehicle and allow for general vehicle tracking. While a lot of people can get behind the idea of never going to the DMV again, not a lot of people are thrilled about the whole “license plate as tracking device” angle"
