Hi. Congrats on being a mod. This is pretty nice but honestly I'd prefer if each of these was a separate post and we could just read it and upvote each individual item. I do like your summary / thoughts though, it's pretty cool.
The other nice (hopefully) side effect is that it can provide the seed activity to hopefully encourage others to also contribute.
I watched a Youtube video about this, and yeah, induced demand affects everything, but when it affects Buses, you get more buses, and that's more efficient. When it affects Trains, you get more trains, and that's more efficient. The only time it gets less efficient is when it affects cars. The moral of the story was: It wasn't the Induced Demand, it was the Cars that were the problem.
