Really depends on the distance and the rides harshness, that's why we have buses and carriages filled with people who didn't take a car anyway.
Definitely not ideal but we can't optimize just for one thing. Putting more busses on demand has really hard scaling problems because of these busses don't appear and disappear like a virtual machine, it needs to be stored somewhere and delivered to the location where that bus is needed. Then you have load-unload problems. This is also why cars that are just like the cars of today but electrical and automatical won't scale too.
You can't really divorce the design of the inhabited areas and the transport systems. This is also probably the reason why the Americans seem so hostile towards public transport. In Europe and even in Asia public transport works fine and the most annoying thing about cars is not that you have to drive them but you have to put them somewhere when you reach your destination.
