In Sweden I have looked up someone's phone number through the info I got from the license plate to notify the owner of a BMW M5 that their 20 years old son was often speeding down the 30km/h street close by my house where kids would cross coming from the metro or a bus stop nearby.

The owner just thanked me, and said was going to have a chat with the driver. Never saw that car speeding nearby again.
