To digress...what about a fine for old codgers (like myself) who can't make it across the road in the time given by the 'green man'? Usain Bolt would be out of pocket around here!
// If the cyclists have a designated part of the highway allocated to them, they should use it //
If you mean they should stick to Cycle paths, no they shouldn't. There is no obligation for cyclists to use them. Often they are more dangerous than in general traffic as buses and taxis are also designated to the same part of the Highway.
