Keep in mind that while everybody here is all outraged about this, nobody else is. Because the experience is so nice. It's the reason why I can search for "prefecture Melun" on my laptop, then jump in the car, open up maps on my phone, Start typing "1" and watch it suggest "12 rue de Gambas, Melun 77320", which happens to be the address of the Melun prefecture.
