I think some scholar nerd in the LTA thought it was 'cool' or 'awesome' to have a driverless monorail system that moves at a snail's pace, with windows that automatically fog up when the train gets too close to residential units.
Besides, being the cheapo Sinkies they are, they should be grateful for more MRT/LRT breakdowns because only then, can they get free bus rides during such occasions. Cheapo Sinkies will go to all extent for anything that is free. Just look at the queue at yesterday's McDonald's Breakfast Day and one just cannot deny this fact.
