On Ride-sharing

"I think the future is actually in ridesharing. So for example, if you compare the ridership of the Southeast corridor, if you look at the person miles that are traveled on that corridor compared with the person miles traveled on I-25 and I-225 that are right next to it, light rail is carrying about 4 percent. Which means you just need to add one rider to about every 20th car, and you could carry the capacity of light rail. And so when you think about these ridesharing apps and so forth, there's a lot of unused capacity on highways. I think that's where the future is really going to go, is to use the automobile much more effectively and sensibly."

However. As Mike Brown of Metro Analytics put it:

“BRT would be great, except for the fact that I am only using the BRT corridor for half of my trip.  The rest of the trip involves to/from my house, which is a mile from the corridor, and the other end likewise is 3-4 miles off corridor.”'

Ride-sharing would certainly reduce the last-mile issue. Fewer people per vehicle, fewer detours, less delay per passenger.  But that requires letting a stranger get into your car . Uber and Lyft have proven this can be overcome. But Uber-Pool has not been an enormous success. Which suggests that for most people, the financial benefits of car-pooling aren't worth the time-costs.
