I have been cycling on road for more than a year. As long as
observe traffic rule, cycle at constant speed, keep to left, should
be quite safe. Actually, it's even more dangerous to cycle on
pedestrian tracks than on road, cause you never know when someone
will pop out from somewhere, in any possible
direction.
Sometimes, I do notice some cyclists (usually foreigners or ah pek)
cycling in opposite direction on the road.
