the problem i have with it, (not read all the posts as real busy at work), but when cycling you have to swerve out the way of them as some are not obvisouly that deep until you get close. Now with MBs whizzing down the buss-lane, i nearly got wacked by one today, is that it may not be the whole which is dangerous, but causing cyclsts to avoid it quickly and being hit by some jerk on a bike
