I was just thinking the other day that we need to have e-ink based license plates. The plate number could be generated and changed every n minutes. There would have to be a government run system that would be able to link the generated number to the owner of the car, but hopefully there'd be some checks, balances and logging on the use of it (ie: a warrant would be required, etc). It wouldn't prevent a government from abusing it, but at least private companies scanning activities would be rendered null.
