In my city you can have video evidence of someone driving up to your house, license plate visible, stealing you property, and driving away and they will take a report, pass it along to the prosecutor, and he or she will proceed to do absolutely nothing.

In Seattle my car was stolen on camera and was later found with a million identifying pieces of information in it, including the thief's security guard uniform complete with name badge, along with receipts at local pot shops with their name and phone number and... nothing happened.

It's hard for me to imagine they're going to running around trying to ticket people for abrupt lane changes.
