Some vehicles do come with built in speed limiters.
Trucks, vehicles used by delivery companies etc will often have speed limiters; presumably it lowers their insurance?
And some production cars offer them as well. As I understand it, this allows them to scam the emissions/range tests, because no matter how easy to disable or how rarely used the speed limiter is, so long as it leaves the factory with the 60mph speed limiter enabled, then it goes through the emissions tests with it enabled.
- bayindirh 3y agoI know. I'm asking why the hard limit is at 250KM/h for most cars, but not at 120. I use cruise control and speed limiters regularly, otherwise.
- Thiez 3y agoBecause many countries have speed limits higher than that? In the Netherlands 130 km/h is allowed (usually only at night), in Poland they have 140 km/h in some places, and in Germany there are many roads where a maximum speed of 130 km/h is recommended, but there is no limit (provided you drive responsibly).
- nikau 3y agoSpeed restrictors are often set to the maximum tyre speed minus a bit of margin. eg. a "W" rated tyre is 270kmh max rated, so the manufacture might set the max vehicle speed to 250. Tyres get exponentially more expensive as speed ratings go up.
