We are in a similar situation, live very close to a school at the end of a cul-de-sac which parents use as a carpark/playground. Often can't get my car off the drive when I need to go to work. In the 12 years my own kids were at the school we must have had a letter/email every 3 months reminding parents to be considerate to local residents and to use the (large, free) car park 5 minutes walk away.
Most don't care. They are special, they are in a hurry, they'll "only be 2 minutes", it's raining, their child is tired, they have a baby. Have heard it all.
Recently had a flier through the door that the local Council are consulting on imposing exclusion zones around schools which would operate 8.45-9.15 and again 2.45-3.15. Only residents with the correct permits, delivery drivers, taxis etc would be allowed within the exclusion zone. All the lazy fucker parents would have to park further away and walk to school or risk a fixed penalty fine.
It sounds WONDERFUL and I've filled in the consultation form saying how much I support it.
(And before any of the lazy fucker parents pipe up that I knew the school was there when I moved in, yes I did. But in the 15 years we've lived here, the school roll has grown from 240 to 440. )
I think that’s really unfair. The people whose streets the problem gets transferred to did not choose to live next to a school with all the inevitable problems that brings. The people right next to the school, for whatever reason, did choose to live next to a school so if there are unfortunately problems, they should bear the brunt tbh.
