If you are talking about governors installed on all US sold cars -those have nothing to do with safety, but rather government dictatorship.
All cars have factory governors, where high performance cars have it at 250 kph, lower powered vehicles can have it lower to not go past the redline.
Posting location and what limiter you are talking about would be a good starting point.
