Car Speeds To Be Restricted By GPS Technology
Article by: rob brady
Date: 3 Sep 2012
GPS technology could be used to exact a 'Big Brother' influence over drivers by restricting the speed at which cars can travel.
The technology, known as Intelligent Speed Adaption (ISA) software, is already on trial in a number of countries and works by cutting fuel to the car engine when speed limits are exceeded. This causes the car to lose momentum, helping to bring the speed back into legal limits.
The system is currently being unveiled in India where, once formally approved, is expected to become a compulsory feature of new car manufacturing.
GPS technology is used to monitor the speed and position of the vehicle, with a detailed map of roads and their corresponding speed limits fed to the device.
Concerns about the sensitivity of the device and the risk of interference have been allayed as any attempted tampering will result in the systems default setting being activated. This reduces the speeds to what one official described as "frustratingly low".

This type of technology has been mentioned a few times.
My worry is that during an overtaking manoeuvre with a car coming in the opposite direction your power is cut. What was a safe overtake is now potentially fatal.
Have they really thought this through ?

...and we all know how accurate road speed limits are on sat nav maps.

The overtaking scenario will be fine as long as you don't exceed the speed limit whilst doing so, which one shouldn't do anyway...

Not for the Spanish market then! I am told that here you are allowed to exceed the speed limit by 20kmh to effect a safe overtake! Not that I would like to put it to the test approaching an officer of the law.
Fancy that in a 30kmh zone.

Ho Ho Ho!!! Last time I saw India on Telly, the nearest thing to a new car was a 1957 sit up and beg Ford Pop.

Does the rest of the world want a 1957 sit up and beg Ford Pop?

Have you not heard of brakes?
It's the pedal next to the accelerator.
Probably not a good time to buy a car made in India...such as Jaguar?

As I recall the highway code used to say you could temporarily exceed the speed limit in order to complete an overtaking manouevre. Now it just says move quickly past the vehicle you are overtaking. Presumably a speed cam could confirm you are overtaking, but a blanket gps control could not. So the implication is that you can only overtake a slower vehicle at a speed not exceeding the legal limit. This makes it a lengthy manouevre - so anticipate sitting behing caravans and tractors for miles.
Edit: for clarity

I agree with your sentiment but say your in a strange part of the country on an unrestricted road. You are overtaking a slower car and you suddenly find yourself passing a speed sign hidden by overhanging trees or the like. |
I agree; if the speed limited activated in that scenario then it could cause a problem.
No doubt there are other problem scenarios which would have to be thought out and handled before the system was adopted widely.
