what i meant was if something so bad happened at school that they'd need an ambulance or fire engine, he'd most likely know about it or get word of it soon enough from somebody
Hmm. Maybe.
But it all depends on how big the incident was, and/or how big the school is.
There were ambulance emergencies at my school that still took half a day for the news to travel across the school, especially if it happened during class hours.
He's probably more likely to know when a fire engine has been called, since that would in most occassions call for a fire alarm being set off. But even so, if he still has to travel across the school and get past throngs of students (likely in a fire when people walk to their safety points), he might still be a nuisance for an arriving fire engine or ambulance.
But yeah, I don't think it's a big issue by any means.
I don't imagine he would cause enough of a reduction in time that it could spell life or death for someone.
I suppose I personally would just decide to park in the regular car park if I wasn't there as an emergency service.
