Well I've yet to get around to doing it though. heh.
But seriously, you tell me to ride on the left, you tell me to filter forward along the curb and then you put freaking holes in the ground there?!? That is one massive liability. I'm aware of the locations of most of these sewer grates, and lets say 40 percent or so(complete guestimate) of these grates have been fixed to where they aren't dangerous to cyclists. But there's still hundreds of them all over sydney and surrounding suburbs that have not been fixed. At least once a week I'm delivering somewhere I haven't been before and encounter one by surprise. I'm just agile enough to at the last moment kind of whip my bike around to take them at an angle or kind of bunnyhop them. If it were wet though that would probably result in a really hard bail. Something tells me that the average commuter on a hybrid does not have the agility or bunnyhopping skills of a 24 year old courier. (although a lot of the commuters here are very strong and assertive riders, you'd have to be with the ridiculous motorists in Sydney. I've heard people says it's not only worse than new york but much worse)
And who really cares if we can all bunnyhop sewer grates and quickly whip our bikes around to avoid danger, we really shouldn't have to. Roads should at least be constructed safely.
