Arrival times are more of a bell curve than evenly distributed, but the point stands with parking scaling down in some measurable way. Does parking drop dramatically? In lieu of filling streets with cars, I have my doubts. Rush hour is a thing, and all of those people will want a ride about the same time. Either streets are clogged in all directions as empty cars try to get in as occupied cars try to get out, or cars wait nearby in anticipation of a request. Again this can be less than current posting demands as the late departures don't need a car nearby until demand had started to taper off, but I doubt the difference is significant (for some nebulous definition of significant).

It would be fantastic if everyone biked 15 miles each way to work. That isn't going to happen short of a global apocalypse, but it's nice to imagine. Put differently, people won't bike to work unless something else changes: a desire to live in the area near work such that it's just as easy to bike as drive, extremely high transportation costs, a social change that makes arriving sweaty as normal as khakis are today, or some other significant change.

I opened a club once that got all the drugs out of Pioneer Square in Seattle simply by putting a bunch of dressed-to-the-nines twentysomethings in their faces every Thursday, Friday and Saturday night.

Were those twenty-somethings there to get the drugs out of Pioneer Square, or were they incentivized to be there by the draw of the club?
