One of the last things I did before sending my daughter off to college with one of the family cars was to "anonymize" her ride.
I removed every parking pass, every conservation center sticker, every bit of identifying information except the license plate. There is absolutely no reason to share any information about yourself with anybody else on the road.
If she wants to put the name of her college on the back window, we'll talk. Every car in that town has that decal. Her car would stand out if it didn't have it...
