Reason is a bit short on facts from time to time, aren’t they.
The bus is as old as the streetcar, frankly, whether motorized, electrified or horse-drawn. What is wrong is how governments and their politicians of every level make both technologies (contemporaries of each other, remember) into political footballs over who can spend the most on them.
But Reason, if they so feel like it, can play the game with the politicians instead of telling it straight.
Busses are obviously more flexable wrt routes. A dedicated ROW could provide better throughput for the express routes.
Jeepney's are not only cheap but amazingly effective. millions of daily riders get from here to there cheaply.
