I think this article misses the one big problem (as I understand it). It's that schools need to dismiss the kid to their parent. I have family in North Carolina and I understand that cars have the family number displayed, and someone with a radio communicates to the school staff "Car 315 is here", they then find that kid and dismiss them. Just do away with that. When the bell rings, send the kids outside and they will just find their parent. That's how my kids school works and there is no traffic jam.
