Guest host Tim Halbur, formerly of Planetizen and CNU fame, joins me this week to chat about the process engineers use to designate speed limits, as recently examined by Nate Silver’s FiveThirtyEight. We’re 85 percent sure it’s not good.

We also get into a discussion about Jared Green’s article on whether delivery trucks should be kept in mind when designing complete streets, or if we should redesign trucks to be more human scale.

And finally, Tim gets lost in one of my rambles about how ride hailing isn’t leading to the “disruption” of transit, on the way to talking about the Airbnb-ification of private parking spaces.

As a bonus, you may or may not hear how my college teammates sold parking spaces to fund end-of-the-season parties or how the San Francisco Chinese New Year Treasure Hunt is the best thing ever.

Guess you’ll have to listen in to find out.
