In Europe, it's very unusual for a kid older than ~9 years to be driven to school.
Here in the UK there are parking restrictions around practically every school to stop parents clogging up the roads to drop off or collect their kids. I'd suggest that's evidence that a lot of children still get taken to school by car.
I have to anecdotally disagree. I am living near to a big high school. Every morning parents, primarily mothers, drive their high school kids into school.
One has to know that every 10 minutes the train stops at the school as it has their own stop.
Busses also stop at school.
Nonetheless the amount of kids in their teens being driven to school by parents is staggering.
I also lived next to a high school. Anecdotally I can say that the amount of kids being driven to school has risen. There is a huge traffic jam now every morning, people in the nearby buildings have adapted to either leave 30min before or after the traffic jam. It definitely wasn't as bad when I was a kid.
When I was 9 years old in Europe, I was walking to school almost two kilometers on my own. And since that age I've never been hauled to any school by my parents using any means of transportation.
