I believe there is way too much value judgement placed here.
If you have two checkouts, people will use whichever one is faster (assuming everything else is equal). Make one faster, and people will shift from one line to the other. Though, to make it an even better analogy, make one line shorter, and people will start coming in from off the street rather than switching lines.
A much better example - telecommuting. IF commute is bad, one is strongly incentivized to have some work-from-home days. If the commute time is improved, then that incentive disappears and one would then consider commuting daily.
Induced demand I think is generally all about the idea that when something is painful - people don't do it. Take away that pain point, and people come. I don't begrudge people too much for driving, as an example I'll note I do my errands on a bicycle. As such, I'm strongly incentivized to make many stops and fewer trips. Meanwhile, I've noticed that people in my family will make a car trip errand as soon as the need comes up. "Oh, I need to go to the grocery store." They get back, then realize they also needed to go to the hardware store, drive out again real quick and back when had there been more planning, the two trips could have been combined. Switching to a bike is an extreme example to avoid the excessive/unnecessary trips that are made simply because it is so convenient. If the drive time were tripled, then there might be a behavior shift to group errands together. Why do so though if it takes just a few minutes to make the individual trips? Eventually the cost of the trip is sufficient that a person will start conserving, avoiding that cost (which can be: travelling in off-hours, grouping trips together, not doing a trip altogether, finding a different mode of transport, removing the trip by moving, etc...)
