Parking in primary schools is always limited, at my DS's school people decode to double park and block others in if they don't turn up early enough. Community police do random checks and move people on and get ranted at by parents who are being moved.
I always turn up early to get a space and my DS is let out early due to his special needs and I regularly find myself blocked in by someone and having to wait ages with a screaming child till they come back from picking up at the normal times.
For this reason I was really pleased to be told DS would be awarded a blue badge as he is now on high rate mobility allowance as I can park in the disabled space which is further away but noone will block me in.
However I won't use this space yet (although almost entitled just waiting to receive the badge) as I haven't got the badge yet. But it frustrates me when I walk past parents who I know have perfectly healthy children and are healthy themselves with no blue badge using the disabled space.
Just a rant, sorry.
