I have an Odyssey, too, and it's pretty good for a mini-van. We got it because dogs, not kids, but many of the use cases are similar.
I do miss my Fusion Hybrid that I traded in for it, though. Pretty car, and I liked paying a lot less for gas.
Obviously it would be cheaper for education districts to band together and commission their own textbooks that cost $0 to distribute once written.
That is an oversimplification, to say the least. Even if you have a collection of districts who paid for the development of a textbook, it still has a non-zero distribution cost once it is complete. It still needs to be printed and delivered. If you want to go without actually printing it, you have to pay for the bandwidth to host it so that people can read the electronic copy (and then come up with a solution for kids who aren't connected to the internet at home or are disabled in a way that makes computer use impractical). Parents will complain about errors and ommissions in the book which will end up dictating rewrites.
This is not a small thing you are asking for, here. Your proposal then requires the school boards to fund such productions for every topic of every grade - in some cases multiple levels of one subject for each grade.
But the school boards are strangely disinterested in this option.
Primarily because the school boards aren't in the business of writing textbooks or funding the creation of the same.
So, be aware of your audience?
Or, beware your audience. Though on the topic, while it's not the most concise construction, signposting something you find interesting so that the reader pays extra attention (or even just a different kind of attention) to it is certainly common. I don't know if that makes it acceptable, but I tend to think it does.
A thought that made me laugh, how does one say "Patience is a virtue" in the original Klingon?
U.S. Senate Thursday, Sen. Jeff Sessions "Alabama-GOP" insults US and Alabama. He supports exporting jobs from the USA, importing foreign science and technology workers, and enslaving illegal immigrants everywhere in the USA. This is typical GOPolicy.
Kleeneness is next to Godelness.
