<< …one slows down as does the driver behind and closes the gap, as we all do in these circumstances. >>

Hold on, that’s not right, Is Mise.

You slow down in accordance with the slower speed limit, and you expect the car behind you to do the same…without coming right up close behind you.

<< Now if a picture is taken how does the driver of the photographed car prove that he was driving in a safe manner and was being law abiding and courteous? >>

Firstly, if you are slowing down gently, having just passed a speed limit sign and hence gone from one speed zone into a slower one, then there is no excuse for the vehicle behind to come right up you.

Secondly, there is no excuse for tailgating at any time. A vehicle may come up close behind if you slow down very quickly. Then if they should pull back. If they stay right up you, then they are driving very poorly and illegally.

Thirdly, even if you do drive in a less than ideal and courteous manner, that is no excuse for the driver behind you to do the same.

One of the basic principles of driving is to realise that there are a lot of poor drivers out there and to have patience, and to certainly not set the law aside and drive dangerously or offensively as a result of someone driving in a less than proper manner.

<< Then there would be the court appearances, the possible appeals… >>

The whole idea of cameras is to record hard evidence. This would surely mean far fewer challenges and court proceedings, as well as much less opportunity for either the complainant or offender/defendant to lie or exaggerate.

Ideally what is needed is an integrated camera system, with at least three cameras. One out back, one out front and one on your speedo….. and possibly one out either side as well. If you could get all three or five cameras to record onto one screen, it would simply be a matter of finding the piece of recording you want, and you would have the full picture, of tailgating, dangerous overtaking, etc, along with the speed you were doing, all presented together.

Police have caught offenders with in car cams, as well as saving courts time in finding the real story.

Car cam offenders get plenty of air time on tv as well, to show people the attitude of some drivers out there.

Cars need black boxes for speed checks.

Police cars started the craze recording people they pull over, and for chases.

There is available a "Black Box" that can be installed in any car that holds say the last
5 minutes of video and a days worth of speed and location that could be interigated by
police to prove or clear a driving offence.
It could be made inaccessible to be altered and would sove many he said she said
arguments.

"one is approaching a speed restriction such as at a Road Work site; one slows down as does the driver behind and closes the gap, as we all do in these circumstances."

As we all do in these circumstances.

That is right, you don't wait till you are passed the sign before you slow down.

We have to signs here and you slow down between the signs.
