I have no idea.......
I took BTC->151 just now after a good dinner and a good chat
with a friend.
Its the screechy but otherwise comfy 1995Z (I like 1956L
best!).....was chionging along Bukit Timah when it kena overtaken
by 2776H (dont like this bus...clutch engages too fast = jerky
ride, and intense vibrations at higher speeds = misaligned
axle)...so you can imagine how fast the bus behind went.
What did my BC do?
Crawl. All the way from entering PIE to HG Int.
Still, despite the best efforts of 2776H, both buses arrived at
HG Int at the same time, illustrating traffic constraints at peak
hour.
