Ok, here's one that unique to where I live. I drive by 2 schools on my way to work. 1 middle schoole and one that is a middle school and high school in the same lot of land. It's a rural area, and there's ALWAYS a line of cars at the school, as it seems very few people let their kids ride a school bus these days.
School # 1 is always busy but not too bad to get by. School #2 however is insane. The street by the school is a 2 lane with a center turn lane. No lights to allow people to enter or exit the school parking lot. There is usually a long line in the center turn lane waiting to turn into the school, while there is also a long line in the parking lot trying to get out of the school and in a lot of cases cross traffic.
My peeve, and it happens frequently every morning. Someone will stop and allow the traffic waiting to turn to go. This of course opens the flood gates and it ends up stopping traffic for several blocks, even out to the main thoroughfare clogging the 4 lane main road. A lot of times a car will stop to let someone turn and after about a dozen or so cars go pass, they don't even turn into the school but continue down the street!
Makes my drive to work here, 10 miles from my house, more stressful than when I lived near Eastgate and took 275 to Blue Ash!
But maybe it's just me!
