I'm throwing it in for the sticklers as an example of something which truly is induced.

They wouldn't be driving for leisure in those geographic locations without roads with low traffic existing. The demand requires a certain low utilization for this cohort.

Also, as someone who lived next to the convention center (and thus i5) in Seattle for ~5 years, there are absolutely people who will drive down i5 for leisure driving. Lots of people racing or otherwise speeding. Hell I would do the same (minus speeding and reckless driving) along 76 and the Schuylkill when I lived on the east coast. Heck some of the biggest opposition in Seattle to tearing down the viaduct (damaged by the nisqually, unlikely to survive another earthquake) was from people who 'would miss the view/drive coming into the city's, and would wax poetic about their literal Sunday drives down such, especially right at sunset.
