I defer on Smart Bus. How do you do a pilot with less than 10 buses on such an expansive route. Does not make sense to buy  a smart card then keep fighting for other matatus since you have no idea when the next smart bus arrives. So the Smart Bus, given it requires the cards, ends up with no passengers at all. If they guaranteed me that they would be buses every 15 minutes, I would probably have bought one, but why buy one if it operates like a normal Matatu?
