Meandering up to our local pool/school earlier, about an hour before kicking out time, it was obvious that the car park is already overfull to the extent of staff parking on the double yellows of the access roads and driveways. I didn't count them, but that's a lot of cars for a modest secondary school. It's amazing how things change – when I was at school mumble years ago, there was space for about a half-dozen cars at the end of the playground. I guess some teachers parked on surrounding streets. There was no vehicular scrum though, most kids walked themselves or mums' (always mums') gathered outside. Of course, when the parents turn up, you may as well be starring in a new Mad Max movie.
To be fair, the school is a victim of the build-on-the-edge-of-town phenomenon (the better-located schools having been deemed unsuitable, closed and sold off cheap to property developers some years back). That said, it's not a big town and much of the catchment area will be within 20ish minutes walk, there's a school bus, and evidently, the barbarian hoards who walk past my house are getting the TfL bus down the valley and walking up the hill.
But anyway, I wouldn't ask any child to cycle there, even crossing the road is a bit fraught – it's a wide, 40mph road. The only saving grace is that at 8.30am and 3.30pm it's a line of slow-moving traffic.
All-in-all, it's a bit grim.
Very different in the US (though like everything it depends on the town, county, state etc.) – the local high school near my place in Connecticut had a drop-off area, but you needed a permit which you'd only get if your kid wasn't on a school bus route. Parking near the school was a serious no-no, the police were keen to issue tickets (it's how the town was funded) and under State law, all traffic violation tickets are double in a school zone. Which considering it's the US, home of the car-fueled society, seemed quite enlightened.
