I don't know how people manage to do this, but for the third time in a month, a driver has cut the corner, driven over the bollard and become totally stuck. She was definitely on the wrong side of the road, but it has happened to people going the other way. OK of course you shouldn't cut corners, but if this bollard is to be a preventative object rather than a retributive one, its got to be a lot more visible/taller. We used to have a series of standing posts which did the job a lot better. ...before that we had an actual pavement! old fashioned concept I know, but quite effective.
