Public transportation:
* Has very high overhead costs
* Forces people into public transportation oriented life schedules
* Is unfriendly to those with disabilities
* Is unfriendly to those who do shift work
* Is a MASSIVE disease vector
* Only effectively serves densely populated areas and makes living in regional areas hell
Autonomous vehicles carrying 1-4 passengers each on direct point to point routes have none of these issues and come with a number of bonuses like flexible demand/supply management and off-peak secondary purpose uses such as carrying deliveries.
Ban public transportation. Stop wasting resources on a dead-end non-solution that literally doesn't work anywhere in the world. People keep pointing to Japan as the shining example of mass transit done right, but none of those people have ever been on a peak hour Tokyo train rubbing crotches against each other and barely able to breathe while station staff help physically stuff people into overflowing carriages.
Go all in on self-driving infra. It's the next 'car'. Mass transit is this generation's 'horse'. We've had a hundred years to get mass transit right and after all this time we've definitely proven it just can't be done.
