Where I live in the US my kids still take “cheese buses” to school that haven’t changed a bit. They’re diesel and you can hear them blocks away. When they pull up with their air brakes going off and their diesel shifting to idle it sounds like one of those spice miner things from Dune going to work.
If they ever go electric I’m not sure how we’ll know it’s time to take the kids out. Won’t be able to hear them coming.
