There are lots of experience sharing by cyclists who have been "saved" by the helmets. I believe there are also many cyclists who don't wear helmet hadn't experienced any events where a helmet could have saved them. However, virtually none of the latter would want to share that, even touching woods with as much skin as one could. Also, sharing such is not helpful. Thus, this is not a helpful post :P
The junction between Balmoral/Anderson/Stevens road is one of the many uniquely Singapore junctions. There is no pedestrian crossing across Stevens on the west side, probably because most cars from Balmoral Road waiting at the junction will be turning right into Stevens Rd. Furthermore, there are two long periods for cars travelling straight along Stevens Road and those that are making right turn into either Balmoral or Anderson roads. All these lead to long wait for most pedestrians, and it is quite common for many to cross this junction diagonally. Currently, doing so is illegal, but I think quite safe because of the followings:
The time allowance for the two right turns for cars along Stevens Road into Balmoral and Anderson roads is sufficiently long.
The right turn from Stevens Road into Anderson Road is not at the junction, but some distance from the junction, giving a wide space between the outer curves of the two right turn paths.
Although the junction is not small, but the diagonal distance between the two corners (north and south) are not too far.
Not exactly zigzag as bicycle just need to be ridden through it diagonally. It has some use in slowing down but I still think the potential hazards it creates are much more than its benefits. Anyway, I guess some would still use the cement covered drain portion (on the west side) and the grass patch (on the east side).
The blue/white bollards and chain
As the PCN hit Merpati Road, there is a pair of alternating blue/white painted bollards with chain blocking off. This is new to me. Older Google Streetview show it was black/yellow previously. I'm not sure why and the meaning of blue/white paint. Here, I find the chain is too thin and might be missed out as some may not notice the bollards as the opening is quite wide.
The distance markings
I like the distance markings. Previously it wasn't clear the direction relevant to the distance labelled. This one is quite clear to me.
Sheltered walk way
The roof of sheltered walk way are not very heavy, and I think just have support on only one side should suffice. Especially on narrow pavement like the one along Aljunied Road here. Yes, cycling on pavement is [still] not legal, but the crowdedness would be worse if bicycle users obediently dismount and push on pavements.
