OK, I'll engage further.
Parents can and do also decide other things that can be dangerous for children are OK - buying them electric scooters, drinking, using drugs, going out with adult men, leaving them home alone. The fact that they are the biological parents does not make them automatically right and must be the sole arbiter of what is safe at all times.
Council staff can have motives related to ideology or personal performance targets that pay no attention to the realities on the ground. An example of this would be a council who has set certain targets for cycle use without considering the safety of anybody cycling or of pedestrians. Somebody planning a school, looking at the area, knowing the area, knowing what dickheads drivers are in the mornings, consulting experts on the transport strategy for the school (as they all have to determine how students will travel to them - it's what causes extensions of bus stops, increases in services, alterations in routes, for example) is perfectly capable of realising that whilst Nigel and Anna (Nigel, mostly) might think that it's perfectly fine for Barnaby to cycle into school, Nigel is six foot five and wearing lycra of a shade of orange roughly consistent with the light of a thousand suns, whilst Barnaby is four foot eleven, wears all black and won't be visible from the driving seat of an XC90 at 7.25am when the driver's youngest is kicking off in the back seat, never mind the HGVs and vans that also hammer it down there every day. And that the so called safe bus lane is actually full of parents dropping their kids off every morning, so said Barnaby would actually be weaving in and out of the vans and cars whilst avoiding being taken out by car doors.
Telling kids that their friend is dead is a really shitty part of the job. Really, really shitty. We don't want to have to do it. Each time, each call we have to make or receive, each empty chair, every time the MIS has to be updated to show a child is dead, the removal of their name from the register, reprinting the fire sheets so that nobody calls out a dead child's name, redoing seating plans, making the notification to the local authority, the inability to make it make sense and the faces of the kids, their families and your colleagues, each day dealing with the aftermath, is seared into your psyche forever.
There are many things that are terrible about some academies. But saying it's not safe so we will not permit cycling here, whatever the council says, is not one of the terrible things.
