Why not put a govenor in all vehicles? If the max speed in Canada is 130 then make the cars go only 130. If you are caught in a car with out the govenor the car is destroyed. Period.
THE QUESTION: Why do ordinary cars have speedometers that go to twice the legal maximum speed limit? Mark Mietkiewicz of Thornhill, Ont., wants to know.
THE ANSWER: Different jurisdictions have different highway speed limits, writes Peter Viney, manager of public relations at Volkswagen Canada in Ajax, Ont. He says both France and Italy have maximum speed limits of 130 kilometres an hour, while Germany maintains stretches on some of its autobahns without any speed limit. So a vehicle sold in markets with different speed limits would most probably feature the same speedometer to reduce manufacturing complexity.
For instance, he writes, “the speedometer on a 2010 Volkswagen Golf sold in Canada ranges from 0 to 240 km/h, and is identical to that of the one sold in Germany.” He adds that the top speed of most vehicles sold in Canada is electronically limited, meaning the engine's control system will cap the flow of fuel at a certain point to limit the maximum speed. “This is [usually] due to the speed rating of the original tires supplied with the vehicle when it is new.”
The maximum speed of the 2010 Golf sold in Canada, for instance, is electronically limited to 209 km/h, although you can’t go that fast on any public road. “However … racing and rallying enthusiasts do take their vehicles to private raceways and tracks under strictly controlled conditions” that allow them to travel at greater speeds than those posted as limits on public highways.
Patrick Girard of Ottawa notes that if the speedometer indicates a top speed (say, 200 km/h) twice as fast as the legal limit, it puts the legal limit in the middle of the dial, where it is easy to read. There is also a marketing angle, he says. “Many people, either consciously or unconsciously, believe that a car with a very high maximum speed on the speedometer is a more powerful, attractive car than one with a lower speed.”
