I'm not sure about the state of automatic license plate scans in Germany but it's a huge privacy issue and there was a big uproar when they were first introduced on some motorways for enforcing tolls for large transport vehicles. Germany is generally very anti-surveillance. Even so, vehicle insurance doesn't come from signing the right documents. In Germany you don't get the seal on your license plate without passing mandatory regular inspections.
