Joking aside, I think every car should have in its GPS junior schools as POI and slow down automatically in proximity. I liked the way they do this in Malaysia - some distance from and beyond the school the road area is hatched where you're required to drive slowly and are not allowed to park.
Where I live, most junior schools are between posts with a picture of a squid on top and those are always accompanied by a 30 km/h speed limit. Most of the time they elevate the crossings as well which stops drivers from approaching them too fast and damage their wheels.
I prefer this kind of signalling - it helps you if you're in an unfamiliar place to be aware that there is a high chance of kids on the road, and driving is all about risk management.
