The moia service in Hamburg Germany offers virtual stops which is the next step I would argue. The bus follows a different route and stops every time based on the need of current passengers
This is just a shared taxi, no? They have existed for a long time at small scales. For example airports and hospitals often have such services.
I was going to say this! Moia is pretty awesome
What does that mean? The links doesn't help explain it much?
In the UK/London there are some bus routes where you just stick your arm out and the bus will stop to get you where you stand ("hail and ride") and equally you can just ring a bell when onboard and the driver stops as soon as there is somewhere convenient to let you off. The route is fixed though.
Is it that sort of thing?
