True , some of those points i didn't take into account, but:

> Similar trip

I once read a research paper about "demand responsive transportation" that simulated such route aggregation in realistic traffic over a large part of a city(probably in finland), and got similar results with regards to route efficiency, as far as i can remember. Can't seem to find the paper , will look later again.

> induced demand

It's really hard to predict how much induced demand this will cause ,because:

1.Big efficiencies - hard to imagine all we be "eaten".

2.It lengthens trip time.

3.Once it's running, we have a software layer on top of transportation, which might be a powerful new tool for transportation management - which might greatly affect demand.

> comfort

You might be right on that, although for bus riders the decreased travel time will surely be worth the extra inconvenience.
