Yeah, this isn't sports, but it relates to driving, and we drive to stadiums, right? So whatever happened to the courtesy wave? I let a guy in from an on-ramp, and I get nothing. I've even been flipped off because I waved at them first after letting them in. What's happening to us that we've entirely forgotten how to be courteous? If someone obviously slows down and allows you into a lane, wave to them and say thanks! It lets them know you appreciated their kindness, and they're more likely to do it in the future. If everyone did this, there'd be less jerks on the road (and less accidents!).
