To maintain the level of throughput we expect and need, trains have to run to a rigid schedule. If things were re-jigged so that trains could leave a bit late for some reason or other, the resulting reduction in throughput and corresponding passenger miles would outweigh your inconvenience. After all, trains drove the mass adoption of accurate timekeeping.

This is accounted for in my "panoptic computronium cathedral"™ with reconfigurable and individual tube systems for transporting individuals at high speeds [1]. The AGI decides who needs to be where and for what purposes and then reconfigures the tube system to accomplish the task. It is much more efficient and does not require any time keeping devices.

Sounds very similar to the existing road infrastructure.

The tubes prevent accidents, that is the main innovation.

You’re still going to hold up other people if you stop to chat or stick your arms out of the tube.

The AGI takes care of that as well. The tubes are reconfigurable so you can't be where you're not supposed to be according to the AGI's plan. Even if you're chatting the tube will suck you up and transfer you to the required destination.
