Uber is experimenting with letting riders wait longer in exchange for cheaper fares

So if you walk longer or wait longer, things become cheaper, huh?  I guess that sorta makes sense, but this is starting to become very confusing.  I just want to get to places.

"Good things come to those who wait for their Uber. The ride-hailing company has started testing a feature that gives riders the option to trade a shorter wait for a cheaper fare. “Prices are lower at 17:00,” Uber recently advised an Uber employee who requested a ride in Berkeley, California, and tweeted a screenshot of the feature."
