Transportation has a Goldilocks problem. At one end, there is “this mode is too solo:” the single traveler in a space-gobbling automobile. At the other, high dollar,we have “this mode is too big:” either high dollar, fixed guide-way public transit or high dollar road expansions.  As a country, we’ve institutionalized these two ends, with less interest for the in-between.  But thanks to technology, this is changing.  We are on the cusp of widespread microtransit.
