Do we blame the city when drunks crash their cars in to lane barriers? Or trees?
I don't like those scooters and I think they are dangerous - but even the man in the story admits he rode them many times previously, and knew he was not supposed to ride on the sidewalks. He knew what he was getting in to.
This trend of "no one is ever responsible for their own actions" is not going to end well. When do we start holding people accountable?
