Speeding

The UK currently has just become roads full of speed restrictions and speed cameras. But do speed cameras make any difference the way in which we drive?

In my eyes all i see people do near speed cameras is put their brakes on through the lines on the floor and as soon as there out of the way in the camera they just proceed with the speed they were doing beforehand. So are they really that effective, because they are not reducing the speed of motorists. Below are some statistics about breaking the speed limit, but in fact the majority break the speed limit on the motorway and not on 30/40mph areas.

On the web link below is a section headed "How are drivers affected" which says that it makes people pay more attention to the speed camera and the speedometer rather than the road itself and in a way causing more danger than good.

All in all though i believe they are effective, they manage the roads in a safe manner and have drastically reduced the number of accidents on the road, and im sure have saved many peoples especially childrens lives in areas where it is now 20-30mph. Large amounts of campaigning on speeding has been around saying if you hit me at 30mph there's around an 80% chance i'll live but just by 10mph more you can drastically reduce the survival rates.
People need to think about speeding and not only their safety but others aswel, by speeding you are being immoral by not thinking about the risk you may pose to others such as other drivers, children, animals etc. If you are going to speed you need to make sure you are an extremly compotent driver who is fully aware of all around you.
Im not a driver myself but i know when im in a car and someone over takes me it makes me feel uneasy? Am i the only one it makes feel that way?
