Induced demand is a sign of success: it allows more people to move comfortably between points, and it increases the overall economic activity by inducing more trips.
The only reasonable part of that argument is that lane expansion doesn't increase the average _speed_. And this is indeed true. Instead of lane expansion we ideally should just increase the interconnectivity by building new roads.
In the case of the Puget Sound, I-605 that would bypass I-405 bottleneck is sorely needed.
