AIBU to have rung another school about this?

[Aethelfleda]

I was walking my DCs to their school (let's call it School A) this morning, when the traffic coming along beside us had a lady driving her three DCs to another school (School B). As they passed us (fairly slowly as the road is busy at that time of day) I noticed that none of the three Dc in her car were seatbelted, one in the front and two in the back. It wasn't clear whether they were sat on booster seats (they all looked about 8-10 years) or whether they were siblings or a carshare. They definitely were not wearing belts though. They all had school B's jumpers on.
As I walked the DCs the rest of the way it kept niggling me how much I am annoyed by parents that don't belt their kids in, mostly cos it's not fair on the kids in the event of a crash. Those kids clearly were used to not belting up as they were old enough to have done their belts had they wanted to.

When I got home I decided to ring School B to explain what I'd seen and ask if they could please consider some sort of seatbelt safety education for the kids or a small word in the next parent newsletter. I know they have no power over what parents do outside school but maybe a bit of education in the school could help change behaviour of the kids?

The lady at the school sounded a bit when she realised I wasn't a parent at the school. Was I being U to ring them?

I don't understand how people can't see the reason she called the school. She didn't have the number plate to call the police and noticed the children attended the school from their clothes.

What would you have done - used an emergency sniffer dog to track them down? Run after the car? Seriously - the only way to get the message to the person in some way was to ring the school. Seemed logical to me.

I don't think YWBU. People that don't wear seatbelts get right on my tits. Anyone that doesn't make their child wear one is a complete moron and so are the adults that don't. Although if they do have an accident and only hurt themselves (the adults) then I think that we've made some progress to cleaning out the gene pool a little bit.
