I live near a lovely city which would be a wonderful place to shop if only people kept to the rules.
It's impossible to cross from one side to the other without risking injury from cyclists who think the rules don't apply to them. It gets worse in the school holidays as teenage cyclists/scooter riders/skateboarders join in the mayhem. Plus smaller children are also on scooters weaving in and out of people and also into people. 
Yesterday I saw a child aged 6/7 plough straight into an elderly man knocking him off his feet. The child was going to scoot away but a woman grabbed his scooter to stop him but the child ran off. Another person phoned for an ambulance while some of us did what we could for the poor man.
The boy and his mother arrived and she demanded the scooter back and said the boy had shouted to the old man to get out of the way so it was his own fault. 
There are quite a few "security" people patrolling the precinct and they move on buskers and beggars, surely they should also be enforcing the pedestrians only rule? And surely parents shouldn't allow their children to take scooters into a crowded city.
