This is for the critics; lets highlight the problem more clearly.

Assume that you are leaving Sainsburys car park and that you want to exit onto Honor Oak Road. You head up the hill and get almost to the narrow bit at the top when a white van (just an example) turns into Manor Mount, illegally. When there are cars parked either side it is difficult for two cars to pass. If you are driving up the hill lawfully it is often the case, as it was with me a few weeks ago, that you may be forced to reverse down the hill to let the offending vehicle pass, not just slightly perturbed at this drivers flashing his lights and hooting at you and making it clear that if you don't get out of his way fast you may find yourself bumped down the hill. If you are really unlucky the other driver may wind down his window and yell expletives at you and your child at not getting out of the way fast enough. The fact is that a car coming down a one way street, especially when you are not expecting it, is dangerous as its not supposed to be there and people base their driving on that assumption. Shall we all then just ignore roundabout signs and go round them anyway we feel like it?

Also think of some potential scenarios where a pedestrian is crossing the road oblivious to a car turning into MM from HOR as he/she is not expecting traffic to come from that direction. And if they are not looking in that direction, what are the possible consequences to that person?

And lets not forget that someone was nearly beaten senseless a few years ago on this stretch of road for daring to approach offending drivers.....

I'd be interested to hear why gingernuts considers fines to be so useless- surely they are the only solution and one which is widely understood? The vehicles are usually registered to some owner even if they are not insured/licensed so its likely that someone will be feeling the pinch. I think its much too late to be concerned about CCTV- it absolutely everywhere and we are monitored 24/7 by a range of means. We even now thanks to google street thingy can have our homes studied on the internet by potential criminals.

Londondrz, I am sorry to hear what happened and hope that you get better soon. A friend of mine has had an accident on her motorbike recently and fortunately has only had a dislocated knee, but this has rendered her immobile and off work for many months. It doesn't take much injury wise to significantly disrupt a life and personal finances.
