To Markass, thanks for the kind words. I imagined the series to be 2-5 pieces long, but these people are so obnoxiously wrong about everything that I felt I just had to keep going. I can't quote your post for some reason, but I did have to respond to this.
"The video isn't that bad but I notice they drop the "people will fill up its capacity" argument entirely and start talking about things in terms of costs and benefits like a mature adult instead of going "JUST ONE MORE LANE BRO" like a spastic. So at the end of the day the "induced demand" argument isn't even a real argument and it just sounds like one so they can dunk on cars because cars bad. If you have to radically change your argument to make it make sense then it's a terrible argument and should never be used."
Yes, but they still do
proportionally induced demand in favour of whatever public transit fetish they have currently going. Remember, it's very reasonable for a small percentage of latent demand, or even a large percentage of latent demand to be satisfied with a new highway. What's not reasonable is when they look at buses that are already at a dismal 5% average capacity, and then say "but if we make them run 10x more often we'll get 10x more ridership because muh induced demand." You might find you have the exact same number of riders and rider-hours. Or maybe you got 1% more riders, so instead of buses that are 0.5% average capacity, they are 0.505% average capacity because Dave and Chris occasionally ride the bus now. Our 10x increase in buses resulted in 1.01x total ridership compared to the start.
If the buses were at 90% average capacity and you increased the routes by 10x, it would be reasonable to not expect them to be at 9% average capacity, what they would be if no new ridership emerged. Perhaps they'd be at 45% average capacity, since there are undoubtedly many people who want to take the bus but won't because they're full. In this case our 10x increase in buses resulted in 5x total ridership compared to the start.
It's the assumption of infinite demand that gets me. If everyone could teleport, we would not take infinite trips.

But anyway, even Vox made an entire video around the premise that Boston deleted a highway when they literally never did this even a little bit, instead building it underground.
