A speed limiter is a governor used to limit the top speed of a vehicle. For some classes of vehicles and in some jurisdictions they are a statutory requirement, for some other vehicles the manufacturer provides a non-statutory system which may be fixed or programmable by the driver.
Intelligent speed assistance technology, or ISA, uses GPS and sign recognition to prevent vehicles from exceeding the speed limit in a given zone.
The study concluded the increase of speed limits not only increases the speed of vehicles but can also generate additional deaths: "A 5 mph increase in the maximum state speed limit was associated with an 8.5% increase in fatality rates on interstates/freeways and a 2.8% increase on other roads."
In 1901, Connecticut was the first state in the United States to impose a numerical speed limit for motor vehicles, setting the maximum legal speed to 12 mph (19 km/h) in cities and 15 mph (24 km/h) on rural roads. Speed limits then propagated across the United States; by 1930 all but 12 states had established numerical limits. [12]

ISA was born in France when Saad and Malaterre (1982) carried out their study of driver behaviour with an in-car speed limiter. Actually, they did not really test Intelligent Speed Adaptation, because the system did not automatically set the correct speed limit; instead drivers had to set the limiter themselves, and, rather like a cruise control, they could set it as they chose.
A new car knows the speed limit. With a bit of programming it could be made to never exceed it. Starting this year, new cars in Europe will give drivers an audible alert if they exceed the speed ...
