Scanning cars in Dutch cities are taking similar rigorous action against illegal parking as 18-year-old Niclas Matthei does in this country. Visitors from Germany should be careful, because the traveling policewoman doesn't stop at tourists either.

Anyone who gets caught can expect a hefty fine to follow them across the national border back into Germany. There are 75 of these scanning cars in use in the Netherlands alone, and there are now between 200 and 250 vehicles across Europe. In terms of service time, it only takes a few seconds for the first car to be identified as illegally parked.
