This morning I was riding as a passenger on I-80 W and was subjected to some absolutely indisputable indecent exposure around 9am somewhere between Hackensack and Denville. My friend was driving in the left lane so all vehicles to the right of us were super brightly lit by the sun coming up and across the highway—she noticed a guy in the right lane craning his neck and making faces (she thought he was yelling at her for something driving-related) so she asked me if he was still doing it so I look over and TO MY HORROR he’s now thrusting his entire naked pelvis as high as his steering wheel while violently wrenching his extremely flaccid penis. It was clearly no coincidence (time of day, direction of traffic) that he was lit up brighter than a movie screen, so I imagine he does this often or maybe someone’s able to get his plate to report him? Of course he slowed down and immediately exited so I couldn’t act fast enough. It was a white guy with super short/buzzed hair (possibly balding) in a white t-shirt in a white sedan. I know, super distinct, but like clearly that’s on purpose, this seriously seems super thought out/I get serial flasher vibes. If there’s nothing to be done, then maybe at the very least someone will see this?? Idk, but any suggestions as to what to do would be awesome. And if someone tries to catch your eye on the highway just ignore them cause they might be waiting to expose themselves to you in a horrifying and grotesque manner.
