Please. If you think this self driving car scenario will deliver lower per trip costs or reduce urban congestion you're not thinking clearly.
Transit was my livelihood for 37 years. The reason the RTD ran low utilization routes was to provide some service to far flung areas of the district. The other reason is that organized right wingers who had no intention of ever riding the bus themselves raised Hell at board meetings so they could have the bus that nobody rode. Then we had to prove to them that it was a waste of resources. They often didn't care, anyway, because they're paying for it, goddamnit!
It's part & parcel of the FYGM headset. I mean, you know, as if a 1% sales tax rate is breaking their tender Libertopian balls.
I never said self driving cars would offer lower per trip costs. That is something you put into your own head. I also never said self driving cars reduce congestion. What I did point out is that buses are limited by their route. If you want to go somewhere that a bus does not take you, oh well. The advantage of a car is that it can take you anywhere from point a to point b.
I can get an uber that takes me to the airport in about 30-45min for about $50. If I wanted to take public transit, I could take the bus, to the train, to the bus for a 1.5 to 2 hr trip. It will cost me about $10. That is 3-4 times as long of a trip for about 20% of the cost. There is simply no way to make that faster in cities that are not dense. Public transit simply cannot compete with trips like that.
