People will talk about induced demand and all that. But those people really just want to be able to get around. The fact that they just don't because the traffic is so bad doesn't mean you shouldn't add more lanes. It means you should add a lot more. Same with the one lane at a time approach. The fact that it didn't work does mean you are doing something wrong, but it maybe that you need to add 5 lanes at a time, not one. Now I'm not saying they should actually do that, just that the arguments against are BS.
A comprehensive public transit system, well maintained and well patrolled is what LA really needs. I am talking Paris metro on steroids. And it is going to cost in the trillions. But it isn't getting any cheaper by waiting.

I always feel like these induced demand arguments are suggesting that adding more lanes means the same number of people are just choosing to do more driving. Maybe, as you add more lanes you create the infrastructure for a city to grow, and it adds more people which then fill up the new lanes. People aren't just going out and buying a new car or rolling an existing car out of the driveway that they were previously not using because a new lane is built. These are net new drivers, who would not be in that city if the infrastructure for them hadn't been built.

Exactly, thank you. If you build a 6-lane highway in Montana it's not going to magically fill up with traffic, thus one can conclude that context is missing from the Reddit-tier explanation of induced demand or that the entire idea of induced demand is wrong.
