Very cool, if true

6) I have a lot of questions about this one. Are the non-driverless buses from Fife to Edinburgh also under-ridden? Do they take the same route? Fife is a big place; if you drive all the way to the park-and-ride lot, might you figure that it's less time and trouble to keep going than to wait for the pokey bus? That might depend on what parking is like in Edinburgh and on how much time and trouble it is to get to your workplace from wherever it is the bus stops.
Lastly, what's the point of a driverless bus if it still needs two people to staff it?
