For those banging on about speed limiters been around for years - have you actuallt read the article because what is being proposed its totally different.
With Governors or limiters (my car has one limits it to 140 or something) you know the limit, it doesnt change therefore if you are doing 5 mph lower than max speed you are careful of a manoeuvre. With these the GPS will transmit the local speed to tell the car to slow down and it appears it will unless the driver presses hard on the accelerator(so there will be a lull). I see they also are saying that it can be turned off but has to be done every journey - a bit like that pesky engine stop you have to press to make the car run normally.
All this is fine, but how long until Big Brother Government decides to monitor you and fine you if you press it or reduce the speed to snails pace and ther eis nothing you can do.
In a way I am all for some sort of speed control, if they really want safety then this is the way. But there are two problems, first being you cannot trust Government, and even less Plod and the civil service and secondly how will Government raise all that revenue currently pulled in through speeding fines?
