Will Sat Nav systems eventually be used to limit cars to the speed limit?

Question

(According to top gear) The new Nissan GTR in Japan is limited to 112 mph but the sat nav knows when you get to a race track and switches the engine limiter off. Will we see this technology used in all cars and utilised by the police, or is too expensive or even safe?

Heres a clip of it

Answer 1

Not in the UK, they make too much money from the speeding fines. Also it would have to be integrated in the car design, and this would but additional liabilities on the manufacturer. The might have to pay the fines if it went wrong/was jammed &c.

It would encourage drivers to put their foot hard down and rely on the speed control, rather than common sense

Answer 2

The technology is also used in on the road trucks by some companies, use to prevent their drivers from getting speeding tickets and also to maximize fuel efficiency.  Cost are coming down, hardware is less than 100 dollars for high volume production if it is strictly one way sat nav (receive) without visual display.    Software and two way systems cost considerably more.  

Will it be used by the police to enforce speed limits in the USA?

That will have to be seen if the politicians can get the courts to allow it as it seems to me it would be violation of the constitution (illegal search and seizure of personal information without consent or warrent)  

Of course speed limiting technology utilized by manufactures is strictly up to them and if you will buy their products.

Answer 3

...you never know....seen a usa car that you had to blow into a tube to check if yove been drinking...

Answer 4

the sat-nav in some current mercedes vehicles will call the police if you're speeding, so yes, indirectly. and odds are, other manufacturers will follow suit. but it's all moot. in the near future, robot cars will be doing all the driving and will be able to maintain much higher speeds than humans can (safely, anyway)
