Sucks to suck!

You joke, but when my parents bought an electric car, the cops in their small town started harassing them. My mom drives like a saint but they keep pulling her over and giving her tickets that aren't valid. She said she's caught them waiting for her to leave the grocery store so they can follow her out of the parking lot and try to catch her doing something wrong. But she doesn't, so they just pull her over anyway. This isn't even in a rural town where people are rolling coal. It's just a small suburb. Why do they care?
