Many cyclists in S'pore (especially expats) tend to be inconsiderate. If you live along Upper Bukit Timah, Dunearn Road, Bukit Timah Road, Ulu Pandan and Holland Road, you will notice groups of cyclists on the road even during morning peak hour. Many of these cyclists appear to either be WFH or do not work, but don't bother to wake up earlier. Instead, they cycle 2 or even 3 abreast on bus lanes, causing the rush hour jam to be even worse.
