Thats why i hate Sg heavy vehicle speed limiter imposed on buses
especially,Should have limit to 65kmh max the best..under 60 carbon
will clogged inside the exaust system and its unhealthy for the
engine too..Once a while engine need to blast to clear carbon built
up..
60 is not so good, BEEP BEEP might start to sound
65/70 better, besides can keep up on the expressways
