Ah, yes, you can hold a baby in your lap, "hands free", but not a phone. Having one of each, I can testify to holding a baby is much more distracting than holding a phone. Also, in the unlikely (but possible) event of a crash - I would much rather have my baby strapped in, rather than my phone. Not saying it's ok to let yourself get distracted, whether due to smoking, eating, picking your nose, calling, texting, talking, playing mahjong or anything else. If Hong Kong was really serious about road safety, they should start by installing usable road signs, and removing the ones that are only distracting. Like which lane to pick, well in advance. Large, clear signs that leave no doubt, even to someone who hasn't been there before. "Keep left unless overtaking" - enforce that one too. So many vehicles, from small motorcycles to the largest trucks - insist on persistently driving in the rightmost lane, regardless what speed they are doing. This means so many will pass on the inside. Very dangerous, but what do you do when a taxi is doing 85 km/h in the right lane on the Lantau expressway?
