Where so I start with this topic...lol. So many things that I will have a secret tantrum about (and sometimes not so secret), two of which are already mentioned in the comments. But I'll choose to go with those who choose to ride their bicycles on the footpath (sidewalk) instead of the road. The clue is the name on both sides of the pond - "foot" or "walk". It is actually illegal in the UK to do so, unless there is a dedicated cycleway (not that common), but still it happens. Grrrrrrr!!
