You'll find buses with no AC in northern Spain today. And it's not ancient ones, but ones running on natural gas: They option then without, making them a hazard in July and August. I've seen one specifically operated to take special needs children to their facility, where we'd argue with the company that the fact that they are special needs doesn't mean they don't feel the heat in the summer.
